About this gig
Something in your .NET application is broken and you need it working.
I'm a full-stack .NET developer with 8 years' professional experience at a UK software company. I fix bugs in C# / ASP.NET / .NET Core applications - the kind that are hard to reproduce, not just the obvious ones.
What I handle:
- C# / .NET Framework, .NET Core, .NET 8/10
- ASP.NET MVC, Web API, WebForms (including old legacy code)
- Entity Framework / EF Core, SQL Server, stored procedures
- React / TypeScript front ends
- Broken builds, failing tests, CI/CD pipelines
How I work:
You send the code and describe the problem. I reproduce it, find the actual cause rather than patching the symptom, fix it, and explain what was wrong and why - so it doesn't come back.
I write tests for what I fix where it makes sense. My last project has around 5,000 automated tests, and I work to that standard.
Send me the details before ordering and I'll tell you honestly whether I can fix it and what it will take. If it's not something I can solve, I'll say so.

I'm a full-stack .NET developer with 8 years' professional experience at a UK software company. I build and fix C# / ASP.NET applications with React and TypeScript front ends, backed by SQL Server and Entity Framework. My work covers legacy .NET modernisation, multi-tenant SaaS, POS and fiscal device integrations, and AI agent and MCP integrations. I find the real cause of a problem rather than patching the symptom, and I test what I build - my last project runs around 5,000 automated tests. I work across UK and EU time zones and speak English and Bulgarian.

FAQ
Do you need access to my repository?
Read access to the relevant code is enough. A zip file works just as well if you would rather not add me to your repo.
What if you cannot fix it?
Message me before ordering and I will tell you honestly whether I can solve it. If I accept the order and cannot fix the problem, you get a refund.
Will you sign an NDA?
Yes. Send it over before we start and I will sign it.
How quickly will you reply?
I work across UK and EU time zones, so usually within a few hours. Send me the details of the bug and I will come back to you with an honest assessment before you order.
