About me

Full-stack developer and QA engineer with a strong .NET (C#, ASP.NET, EF Core, MAUI) and Python background. I build REST APIs, desktop apps, and test automation (Selenium, NUnit), and I run my own self-hosted infrastructure (Docker, Incus, CI/CD). I learn fast, work independently, and ship clean, maintainable code.
