Volunteering System Developer at ReactOS Foundation
Albi, Occitania, France
Summary
🤩
Rockstar🎓
Top SchoolHermès Bélusca-maïto is a seasoned systems developer with 12 years of experience, best known for long-term volunteer engineering on the ReactOS project where he has fixed core kernel subsystems, improved x86 build scripts and integrated upstream work on btrfs and SCSI. Trained as a theoretical physicist (PhD-level) with postdoctoral research in quantum field theory, he brings rigorous analytical thinking and deep numerical/low-level programming skills to OS and systems development. Based in Albi, France, he combines open-source craftsmanship with academic precision—authoring a graphical one-stage installer for ReactOS and contributing substantive back-end fixes to a Windows-compatible open OS. His background in particle physics and trigger/monitoring software at CERN underpins an ability to tackle complex, correctness-critical code paths that span hardware interfaces to filesystem stacks.
