Hiring .NET developers gives organizations access to secure and high-performance solutions across web, mobile, desktop, and cloud. Backed Blackthorn Vision has been building .NET software since 2008 and has been a Microsoft Solutions Partner for most of that time. Our engineers work on Azure, .NET 10, and the legacy .NET Framework applications that many companies still rely on for their businesses.
You can hire .NET developers from us as a dedicated team, as individual engineers joining your existing team, or as a full project team with a fixed scope, with rates and terms agreed beforehand.
Send us the role and we will get back to you with CVs within three business days, after which you can interview the candidates, run a test task, and start when you are ready.
Get pre-vetted .NET engineers matched to your project and ready to start in two weeks.
Before the stack list, you probably want to know how long we have been in the .NET ecosystem, who picks the engineers you get, how fast a shortlist arrives, and whether the people you interview are still on your project a year later.
15+ years of expertise in .NET development
We have worked with .NET since 2008. Our C#, ASP.NET Core, and Azure experts have carried products from the .NET Framework era into .NET 10, and they know the nuances and the traps.
Microsoft-certified engineers
As a Microsoft Solutions Partner, our engineers hold current Microsoft certifications in Azure development, administration, and data engineering, and certificates are available on request when you hire dedicated .NET developers.
Ready to start in two weeks
CVs land within three business days of the intake call, interviews follow within a week, and most engagements start about two weeks after first contact, with the same engineers staying on your project afterwards.
150+ delivered projects
We have delivered more than 150 projects for clients in healthcare, biotech, oil and gas, travel, and fintech, and several of those client relationships have passed the ten-year mark.
Clients that stay with us and are ready to recommend us
Our clients give us the best possible appraisal, which is a recommendation. Our Clutch and GoodFirms profiles carry reviews from the people who worked with our teams directly, and a number of clients came to us by word of mouth. We have built several products for the same clients over the years, which says more about the work than any rating does.
When you hire .NET developers from us, three people review the engagement before it starts: architecture and delivery, the AI layer, and the cloud-native side. They sign off on the estimates, the technical decisions, and who joins your project.
Yuriy Horak, Chief Technology Officer
Yuriy combines .NET and C# engineering depth with software architecture. He has spent years running distributed teams on outsourced enterprise projects. He decides what your team looks like, which engineers fit the brief, how the architecture should be structured, and whether the estimate is honest.
Yuriy works in cloud-native Azure development, current .NET, and DevOps, so he is used to the hardest client questions:
Extend a .NET Framework application or rebuild it?
What will a migration to .NET 10 cost?
Will the current architecture survive the load you are planning for?
If you hire dedicated .NET developers from us, Yuriy is the one who selects the engineers for your project.
Vadym Zhernovyi, Lead AI/ML
Vadym runs the AI/ML division: generative AI, AI agents, LLMs, computer vision, natural language processing, and the MLOps and LLMOps work that keeps them running after launch.
On .NET projects, his team owns the AI layer, which means Azure OpenAI, Semantic Kernel, the Microsoft Agent Framework, and ML.NET where a model runs in-process. This is what most clients now mean when they ask for an AI feature inside a .NET application.
Bohdan Lisovskii, Senior .NET and Go Developer
Bohdan works across .NET and Go on high-load, cloud-native systems: Kubernetes, Docker, REST APIs, deployed across AWS, GCP, and Azure. In code review, he argues about performance and test coverage.
On .NET projects, the cross-language question comes up more often than clients expect, because few enterprise platforms run on one stack. When a .NET system needs a Go service beside it, when the question is how those services talk to each other under load, or when the deployment target is Kubernetes, Bohdan joins the conversation before the architecture step.
Talk to our CTO about your architecture before you commit to a scope.
Some clients arrive with a greenfield build, others with a 15-year-old application. Whichever you are starting from, you can hire .NET programmers from us for a single service or for the whole delivery.
Most engagements draw on two or three services at once. A migration needs a DevOps pipeline behind it, and a new web application needs an API layer and a cloud setup underneath. We scope them together, so the estimate reflects the real cost of the whole project.
.NET web application development
We build ASP.NET Core and Blazor applications, from internal tools to customer portals and platforms your clients log into. Razor Pages or MVC depending on what the project needs, with REST APIs when you have a separate frontend in React, Angular, or a mobile app.
Authentication, HTTPS, data protection, and input validation are built into ASP.NET Core, so the security basics come with the framework and the estimate covers your actual features.
Clients who hire ASP.NET developers for a first web build usually start here, and it’s safe to say that every ASP.NET developer for hire on our bench has shipped production applications on this stack.
.NET backend and API development
We build the backend, meaning the APIs your frontend calls, the services behind them, and the database layer underneath, using REST and gRPC for internal service traffic, GraphQL when your clients need to query flexibly, and microservices when a system has grown too big to deploy in one piece.
Our engineers build in CQRS, DDD, and Clean Architecture. Systems we built years ago are still in service, and teams are still adding features to them.
AI integration with .NET
We add AI features to .NET applications using Azure OpenAI, Semantic Kernel, and the Microsoft Agent Framework, and where a model needs to run inside your own application, we use ML.NET.
In practice, that means search and assistants that answer from your own documents and show where the answer came from. The harder part is the work that keeps them usable: blocking prompt injection, testing how often the model makes things up, and setting a monthly token budget with an alert before it runs over.
Cloud-native development on Azure and AWS
We build .NET services that run in containers on Azure or AWS, using Azure Functions for event-driven work, App Services for hosting, and Cosmos DB where the data model suits it. For distributed systems, we use Kubernetes and Docker, so the platform scales when traffic climbs and keeps working when any part of it goes down.
Infrastructure comes as code, which means a new environment takes several hours to configure instead of a week of manual setup.
Cross-platform mobile with .NET MAUI
We build .NET MAUI applications that share one codebase across iOS, Android, Windows, and macOS, and if your backend is already .NET, this keeps the mobile app in the same language and the same repository as everything else.
The alternative is a separate mobile team writing the same business rules a second time, in a different language, then keeping both copies in sync every time those rules change.
Legacy .NET Framework and .NET 10 migration
We migrate .NET Framework applications to .NET 10, covering outdated dependencies, WCF services, WebForms, and code that has not been touched in years, often written by people who have left the company. We map the dependencies first and migrate in stages, so your application keeps running while the process takes place.
We assess the application first, then estimate the migration, so you see the cost before you commit to the work.
.NET DevOps
We set up the delivery pipeline, including Azure DevOps or GitHub Actions, containerization, infrastructure as code, and automated releases, with monitoring running through Application Insights, Datadog, or Grafana.
We tune the alert thresholds so your team only gets called for problems that need a human intervention. Your engineers get a pipeline they can confidently rely on.
.NET maintenance, modernization, and support
We support systems that are already in production through bug fixing, refactoring, performance work, security patching, and version upgrades, with critical issues getting a response within hours and a named engineer kept on your system.
Some clients keep a small team on retainer. Others run the system themselves and call us when a release is coming and they need a hand.

What to look for in .NET developers at each seniority level
Seniority labels are tricky, because they mean different things at different companies. A senior at a product startup and a senior at an enterprise consultancy have different reflexes, and the title alone will not tell you exactly which one you are interviewing.
So instead of the label, here is what actually sits behind each level: what to expect, what to ask in an interview, and when that level is the right hire. It is also how we screen internally, so it doubles as a description of what our own technical interview covers before a CV reaches you.
Junior .NET developer
Hard skills. Solid C# fundamentals, LINQ, async and await, and Entity Framework Core for data access. They build controllers and endpoints in ASP.NET Core, write unit tests in xUnit or NUnit, and work comfortably in Git with pull requests and code review.
What they will not do yet is design the system, which is why a junior needs a defined ticket, a code reviewer, and a senior nearby when the requirement turns out to be ambiguous.
Soft skills. The most important skill at this level is the willingness to ask questions, because a junior who flags a blocker or asks for another round of clarifications only costs you time, whereas one who works around it privately for a week costs you the sprint. In the interview, ask what they did the last time they were stuck.
When to hire at this level. When you have a senior or lead with time to review and a well-defined backlog. Their value is throughput on specified work: CRUD features, admin screens, integrations against documented APIs, bug fixes with clear reproduction steps.
Budget six to eight weeks before a junior is productive on a system of any size, and expect the reviewing senior to lose about a fifth of their own capacity during that period.
Middle .NET developer
Hard skills. Confident ASP.NET Core work, REST API design, dependency injection, and Entity Framework Core, including the parts where it generates bad SQL. They know enough SQL Server to read an execution plan when a query is slow.
At this level, engineers should also be comfortable in the cloud, which means deploying to Azure App Service or a container, reading logs in Application Insights, and knowing what their code costs to run, while testing expectations rise from unit tests to integration tests against a real database.
Soft skills. A middle developer can handle a ticket that is not fully specified. Given a vague requirement, they come back with questions before they start building. They review other people’s code, spot the bugs that only appear when two features interact, and tell you when a deadline is unrealistic while there is still time to move it. In interviews, ask about a decision that turned out badly and what they changed afterwards.
When to hire at this level. When you need reliable delivery on an existing system that has known patterns. Middle-level engineers are the backbone of most .NET teams, skilled enough to work unsupervised on their part. A practical ratio is two middles to one senior. The senior holds the architecture and the parts that are expensive to get wrong. The middles carry the feature load and review each other.
Note that on a greenfield system, a team built entirely of middles can produce working software, but the architecture often will not extend a year later.
Book a call
Not sure who you need at the moment? We will help you with an efficient team composition.
Hard skills. A senior knows C# deeply enough to deal with memory pressure, allocation problems, and the async bugs that only appear under real traffic. The main difference is architecture, since seniors decide where service boundaries go, work in CQRS, DDD, and Clean Architecture, and can say when a microservice is worth the operational cost and when it adds cost for nothing.
They design cloud architecture on Azure, handle message-based communication with MassTransit or Service Bus, add resilience with Polly, and set up monitoring that tells you which component failed. Give a senior an unfamiliar legacy codebase, and they come back with an estimate.
Soft skills. Seniors review code in a way that teaches, mentoring middles and pushing back on requirements that would create technical debt, and they make decisions that are expensive to reverse, which means explaining those decisions to the people who will live with them.
When to hire at this level. For greenfield systems, for modernization work, for anything with compliance exposure, and when your team needs someone whose judgment you can delegate to. Seniors take on the work the other levels can’t: performance investigations on a system nobody understands, migrations from .NET Framework the original developers left years ago, or security reviews before an audit.
One senior on a team of middles changes the output of everyone around them. Two seniors and no middles usually means paying premium rates for routine feature work.
Team lead .NET developer
Hard skills. A lead has senior-level skills and knows how the whole system fits together. They can explain which services are connected, where the integrations are fragile, how a release gets shipped, and who gets called in an emergency, and they hold that map of the system in their head.
They set the standards the team writes to: the definition of done, the branching strategy, and what a code review is expected to catch. Team leads still write code, usually the most complicated parts.
Soft skills. What separates a lead from a senior is who they talk to. Inside the team, they unblock people, give feedback, and absorb the interruptions so their engineers can finish the work. Outside it, they report status plainly, explain a technical trade-off to a stakeholder in business terms, and say when a date will slip before the timing becomes critical. They also break large work into pieces the team can finish, and push back when new scope arrives halfway through a sprint.
When to hire at this level. When the team passes four or five engineers, when you have no in-house technical manager for the project, or when delivery keeps slipping and nobody can say why. A lead costs more than a senior, and earns it back in the hours your own managers stop spending on chasing status and sorting out who is doing what.
The trade-off is coding capacity. A lead running a team of five writes about half the code a senior does. If you already have a strong in-house manager handling delivery, a senior engineer is usually the better hire at a lower rate.
Industries we serve
Biotech
.NET applications for laboratory workflows, instrument data, and research pipelines, usually with FDA 21 CFR Part 11 or similar in scope. That regulation influences the build more than any technical decision. Every record needs an audit trail, electronic signatures have to bind to the data they sign, and validation documents have to exist before an inspector asks for them.
The data side is where .NET shines here, because instruments produce files in formats that change with firmware versions, volumes climb into terabytes, and analysis has to be reproducible years after the run. We build the ingestion, the storage model, and the processing pipelines, with ML.NET or Azure Machine Learning where a model sits in the workflow.
Our laboratory diagnostics software for Selux Diagnostics supports antibiotic selection for sepsis patients, under accuracy requirements set by regulators, and their team has kept our engineers embedded for over five years.
Real-time monitoring, SCADA integration, and field applications built on .NET, often talking to equipment through MQTT or Modbus. Connectivity in the field drops without warning, a wellsite sends data on a schedule nobody controls, and the application has to keep working through the gap and catch up afterwards.
We build the telemetry ingestion, the time-series storage, and the dashboards operators watch during a shift. Alerting matters more here than in most sectors, because an alert that fires constantly gets ignored. Tuning thresholds against real production data is a big part of the work.
We have worked with a US digital oilfield leader for more than ten years on a web platform that monitors oil and gas equipment and reports on its condition. Ten years on one platform means we have migrated it across framework versions, moved parts of it to the cloud, and kept it running the whole time.
Healthcare
EHR integrations, patient portals, scheduling, and telehealth on .NET, with HL7 and FHIR where systems have to talk to each other. Integrating those systems usually costs the most, because every hospital runs a slightly different configuration of the same vendor system, and the interface that worked at one site needs rework at the next.
HIPAA work is routine for our teams. It includes role-based access, encryption at rest and in transit, audit logging, and the documents an assessor will ask for. ASP.NET Core covers a good part of this out of the box, which keeps the security work in proportion to your actual features.
On the patient-facing side, we modernized a legacy desktop application into current software for dental diagnostics and treatment design, which guides a dentist through diagnosis and treatment planning from 3D imaging.
Travel and hospitality
The examples include booking engines, pricing systems, and customer portals that carry massive traffic. Load in this sector is spiky, since a campaign, a holiday weekend, or a competitor going down can multiply your traffic within an hour, and the booking path has to hold while it happens.
.NET handles the concurrency, and microservices let booking, reviews, and loyalty scale on their own schedules, so a surge in search does not take payments down. Integrations with distribution platforms, channel managers, and payment providers are most of the work, and each one has its own quirks around rate limits, stale inventory, and reconciliation when a booking fails halfway through.
Transaction processing, reporting, and back-office systems where correctness matters more than innovation. .NET and SQL Server remain the default in this sector for good reasons: mature tooling, predictable performance, and a security model auditors already understand.
Every number on a report has to lead back to the transactions behind it, which affects how you model the data, whether you keep an immutable event log, and how you handle a correction to a period that has already closed. Getting it wrong is expensive to fix later, so we put a senior engineer on it early.
From the first call to an engineer committing code, the process runs about two weeks in most cases. The steps below describe what happens at each stage and what information we need from you.
The parts that depend on us have fixed timelines. The parts that depend on you, mainly interviews and any test task, take as long as you need and as your hiring standards require.
1. Discovery call
You spend thirty minutes on a call with our .NET expert, describing the system, the team, your needs, and your limits, and from that our CTO can build a team or select a specialist who matches you best. If we can’t meet your expectations, we tell you right away, during this first call.
2. Requirements and team profile
We describe the role: stack, seniority, and domain knowledge. We also note the hours you need overlapped and the working style that fits your team. Then, we send it to you, and once the role is approved, we select the best fit. This usually takes a day and saves you time on the interviews.
3. Candidate selection and CV review
Within three business days, you get CVs, each with a short note on why this person fits your description. Everyone on the list has already been through our own screening: a technical interview, an architecture discussion, and an English level check.
4. Interviews and test task
You interview the chosen candidates and take as much time as you need to make a decision. You are welcome to set a test task if that is how you normally hire, or skip it if the conversation told you enough. For longer engagements, we suggest a paid trial of a couple of weeks, which is the cheapest way for both sides to find out if it works.
5. Contract and kick-off
We handle the contract, the NDA, and the access setup. The engineer joins your repositories, board, and standups, and starts work in the first week. From that moment, you deal with them directly. We stay reachable and responsible for replacements, holiday cover, and anything you need escalated.
Tips for the successful hiring process
During our hiring process, we are focused on ensuring that every developer we onboard is technically strong and communicative, and shares our corporate values. Here’s what we do:
All our candidates pass a multi-stage screening process that includes CV checks, coding tests, and architecture discussions. We evaluate problem-solving skills, experience with .NET Core, familiarity with tools like Azure DevOps, and understanding of modern software practices (SOLID, DDD, TDD).
Candidates meet senior engineers who assess system design capabilities, familiarity with async patterns, LINQ, Entity Framework, RESTful API development, and Blazor.
We prioritize excellent communication, proactive reporting, and accountability. Our interviews include scenario-based questions to assess candidates’ soft skills and client-facing competence.
Someclients require a 1–2 week trial period before full onboarding to evaluate developer performance on live tasks and make sure that they truly become a part of the team and that the cooperation is comfortable for everyone. While optional, this step is common when there is a perspective for long-term cooperation or tasks that require teamwork.
Once approved during the interview and/or trial period, the developer is integrated into the client’s version control system, documentation workflow, and communication stack, and begins performing as an integral part of your team.
Bottom line
You have seen the stack, the people who would run your engagement, the process, and the work we’ve done. The only question left is whether you want CVs in your inbox this week.
Each candidate we offer you has already been screened on a technical interview and an architecture discussion. You interview the ones you like, set a test task if that is how you hire, and start when you are ready. team, full transparency in processes and communication, and scaling resources as needed.
What is .NET, and why should I consider it for my project?
.NET is a free, open-source framework developed by Microsoft. It supports cross-platform development, integrates well with cloud services, and is known for its performance and security. .NET Core (now unified under “.NET”) is ideal for modern applications, supporting microservices, RESTful APIs, and rich front-end experiences.
What industries do your .NET developers have experience in?
Our developers have proven expertise working in healthcare, biotech, fintech, logistics, travel, oil and gas, and education. Many are familiar with domain-specific standards like HIPAA, FHIR, PCI-DSS, and SCADA integrations. Moreover, we invest in their learning and development, and are always willing to gain new expertise to offer the best solutions for your projects.
Do you offer both front-end and back-end .NET developers, or full-stack developers?
We offer all three. Our developers with front-end experience use Blazor, Angular, or React. Back-end specialists handle APIs, microservices, and data architecture. Full-stack developers are available for end-to-end delivery. You can choose the best option according to your resources and estimated time to market.
What are the different engagement models you offer for hiring .NET developers?
We have three payment models that can be customized based on your budget, timeframes, and team size. Those are:
Dedicated team – full-time resources for long-term projects.
Fixed-price – milestone-based delivery for defined scopes.
Time & Material – flexible billing for evolving project requirements.
What types of projects are best suited for .NET development?
.NET is versatile, so it finds application across systems and industries. Enterprise systems, web portals, mobile apps, SaaS platforms, desktop software, CMSs, API backends, and cloud-native applications – those are all the cases. Now, .NET is widely used in industries like finance, healthcare, biotech, retail, logistics, and the energy sector.
How do you source and vet your .NET developers?
We use a rigorous and time-tested recruitment funnel that includes coding tests, architecture reviews, soft-skill interviews, and domain-fit assessments. We also pay extra attention to cultural fit and shared values. We screen developers for their knowledge of C#, .NET Core, Azure, REST APIs, and modern design principles.
What is the typical hiring process for .NET developers through your company?
The hiring process typically includes assessing your project needs, shortlisting developers, interviewing them, optionally running a trial period, and then integrating the chosen developer into your workflow. Contracts, onboarding, and time tracking – it’s all handled on our side.
