Rockstar🎓
Top SchoolMartin Kourim is a Lead Software Engineer in Test with 13 years of experience, currently shaping quality and validation at IOHK with a strong focus on Cardano core components and real-world blockchain scenarios. He is a Python specialist who brings functional programming ideas inspired by Haskell—immutability, higher-order functions and stronger typing—into pragmatic test automation and backend tooling. His open-source contributions include improving Cardano's cluster tooling and integration tests for ManageIQ, demonstrating both deep protocol understanding and practical engineering hygiene. Comfortable in Linux-heavy workflows (nix, Bluefin) and obsessive about developer ergonomics like Neovim, he blends hands-on scripting with system-level insight. Outside work he mixes family life with relentless tinkering, turning hobbyist experimentation into production-quality improvements.
