I help .NET teams design reliable systems, improve performance and diagnose production issues. I use AI-assisted code review and research, with human verification.
About
Hi, I'm Łukasz. I work on reliable .NET systems and AI-assisted workflows.
I'm a .NET technical lead and 8x Microsoft MVP with over a decade of production experience, including Sonova, Ryanair, Credit Suisse and Volvo. My work covers ASP.NET Core architecture, diagnostics, performance and technical leadership. I use GitHub Copilot, Claude, ChatGPT, Gemini, with particular attention to the instructions, evidence and review needed to trust their output.
Outside work I help organize Wroc.NET, the Wrocław .NET User Group (2,500+ members).
I co-founded Dotnetos (2018-2025) and co-authored courses including Async Expert and .NET Diagnostics Expert. I share practical experience through talks, courses and the blog.
