Full‑stack .NET developer with strong experience in backend systems, debugging, code review, and problem‑solving. I also work with Python at a practical level and can analyze logic, fix errors, and evaluate code quality across different languages.

I build scalable APIs, optimize SQL performance, refactor legacy code, and deliver clean, maintainable solutions. I’m comfortable working with structured tasks, technical guidelines, and detailed workflows—whether in full‑stack development or AI‑related programming evaluation.

Tech stack:
C#, .NET Core, ASP.NET, Entity Framework
