A senior .NET developer, without the hiring delay
Recruiting a senior .NET developer can take months. I can usually start within days. With 10+ years of hands-on experience in C#, ASP.NET Core, Entity Framework Core, SQL Server and Azure, I work as an extension of your team: I take a feature from idea to production, keep you updated every day and leave behind code your team can maintain.
Clients hire me to build new web applications and APIs, add features to existing products, fix performance problems, migrate legacy .NET Framework systems to modern .NET, and integrate payment gateways, third-party APIs and AI services. I'm Top Rated Plus on Upwork with a 100% Job Success Score, so you can also hire me there with Upwork's payment protection.

Modern .NET, done properly
I build on current, long-term supported .NET versions (.NET 8 and .NET 10) and follow the practices that keep projects healthy after launch:
- Clean, layered architecture so business rules live in one place and are easy to test.
- Automated tests for the logic that matters, and integration tests for your APIs.
- Secure by default: proper authentication and authorisation, validated input, secrets in a vault.
- Fast data access with well-designed SQL Server or PostgreSQL schemas and efficient EF Core queries.
- CI/CD pipelines on GitHub Actions or Azure DevOps, with deployments to Azure or AWS.
How we'd work together
We start with a short call about your goals, then I review the codebase or requirements and propose a plan with estimates. Work happens in your repository and your project tool, with daily async updates and regular demos. For clients in the USA, UK, Europe and Australia I keep a daily overlap window for calls; the rest of the work progresses while your team is offline.
If you're still comparing options, my checklist for hiring a freelance .NET developer explains what to look for, whoever you hire.

Frequently asked questions
How quickly can you start?
Usually within a few days of agreeing the scope. For ongoing work I can reserve a fixed number of hours per week.
Do you work with existing codebases?
Yes. Much of my work is improving and extending existing .NET applications. I start with a short review so I understand the architecture before changing it.
Which .NET versions and technologies do you use?
Mainly C#, ASP.NET Core (MVC, Web API, Blazor), Entity Framework Core, SQL Server and PostgreSQL, on Azure or AWS, plus JavaScript, React or Angular for front ends. I also maintain and migrate .NET Framework 4.x applications.

Who owns the code?
You do. All code lives in your repository from day one, and intellectual property is assigned to you.
