Profile

I am a Computer Science MSc student at the Silesian University of Technology, focused on C#/.NET software development, backend architecture and practical engineering.

I build projects that go beyond a single application layer: APIs with authentication, domain logic, data persistence, deployment pipelines, caching, desktop clients, mobile clients, firmware, device communication and real hardware prototypes.

My main stack is .NET, ASP.NET Core, Entity Framework Core, SQL Server, PostgreSQL, Redis, Docker, GitHub Actions and Azure. I also use Flutter, Python, Java and C++ when the project needs a different tool.
