Rockstar🎓
Top SchoolSimon Racz is a Principal Software Engineer with 12+ years of experience building distributed systems, mobile platforms, and cloud infrastructure, currently leading cost-savings, disaster recovery, and security initiatives across ~350 AWS accounts at KPN. Trained as a mathematician from age ten, he brings deep algorithmic thinking to practical problems—from porting Detox E2E testing to Android (used by Wix/Facebook) to post-quantum SSH upgrades and browser-based encrypted file sharing. He has a broad polyglot background (C++, Python, Swift, Objective-C, Java) and a track record of creating paved roads, CI/CD pipelines, and platform tooling to accelerate team migrations to Kubernetes and AWS. Equally at home in research and production, Simon publishes technical write-ups, open-source neural-network packing and pathfinding projects, and shares engineering insights on his blog and YouTube channel. Colleagues rely on him for pragmatic solutions that balance security, scalability, and developer productivity, and he deliberately seeks projects that stretch his skills.
