Summary
👤
Senior🎓
Top SchoolBartek Korczynski is a pragmatic software developer with 12 years of experience building high-performance systems, from low-latency C# backend services to a custom 3D engine and a commercially used desktop IDE. He has a track record of squeezing milliseconds out of code—examples include a 3x frame-time improvement migrating OpenGL to Vulkan and a 7x faster Protobuf encoder released as an open-source MIT library. Comfortable across the stack, he has implemented ASP.NET services with Elasticsearch, multi-threaded C networking, and responsive UIs capable of rendering millions of rows at 60 FPS. His open-source contributions include packet-parsing and game-editor tooling for TrinityCore, showing deep familiarity with binary protocols and game asset pipelines. A former AWS intern and university teaching assistant, he blends production-grade engineering with mentoring and clear technical communication. Based in the UK, he’s currently focused on backend C# roles but stays open to challenging systems-level work.
