He’s a seasoned open-source maintainer (over 1,000 commits to Colobot and contributions to RetroArch’s UWP port) and a repeated CTF winner who’s discovered real-world vulnerabilities. Beyond shipping a Steam/Oculus fitness title and cross-platform multiplayer projects, he’s helped set up engineering workflows, mentored teams, and runs workshops to spread knowledge. Based in Łódź, Poland, he combines a hacker’s mindset with product-focused execution, often converting research-level findings into production-ready features.
