Rockstar🎓
Top SchoolPatryk Wychowaniec is a seasoned software engineer with 13 years of experience based in Koszalin, Poland, currently developing at Transition Technologies MS. He blends embedded systems expertise with DevOps and build tooling, contributing to high-profile open-source projects such as LLVM (improving AVR codegen and assembler tests) and nix-community/naersk (optimizing Rust build and dependency workflows). Comfortable working across low-level assembly issues and higher-level developer experience, he has a track record of fixing subtle architecture-specific bugs and streamlining build processes. Patryk holds engineering and master’s degrees in computer science from Politechnika Koszalińska and brings a pragmatic, test-focused approach to long-lived codebases. A detail-oriented problem solver, he often surfaces improvements that reduce friction for other developers while respecting platform constraints.

Embedded Systems Engineer / Automation EngineerContributions:26 reviews, 13 PRs, 2 pushes in 1 year 1 month
Contributions summary:Patryk primarily focused on enhancing the AVR architecture within the LLVM project. Their contributions involved fixing immediate overflows in 16-bit LDD instructions, resolving issues with parsing and emitting relative jumps, and wrapping out-of-bounds relative jumps for devices with 8KB flash. They also reformed MC tests for AVR and worked on relocation. These changes likely involved improvements to the AVR code generation and assembler.
