.NET Developer · AI Integration · Toruń, Poland

Tip

🟢 Open to Junior .NET roles — Poland (Toruń) · remote or hybrid · reach me below.

I spent a decade in operations before turning a long-time hobby into a career. Now I build production-grade .NET apps end to end — from EF Core data layers to Blazor and React front-ends — and I test what I ship. Lately I'm deep in AI integration: RAG, tool-calling, and multi-provider LLM work.
