Summary
👤
Senior🎓
Top SchoolAlexandre Ratchov is a research engineer and seasoned software hacker with 21 years of experience building robust audio and high-performance computing systems. With a PhD in theoretical physics, he blends rigorous analytical thinking with pragmatic engineering to design low-level audio and MIDI subsystems, device drivers, and real-time synthesis software. He is a longtime OpenBSD contributor and founder of the Midish project, and has contributed backend work to Mozilla's cubeb audio library (including sndio support and latency/format fixes). Currently at ARVerb and freelancing on music synthesis and visualization, he focuses on simplicity-driven correctness for audio plugins and performance-critical code. His background spans big-iron HPC at Bull to live-performance synthesizers, reflecting an unusual combination of kernel-level systems work and creative musical engineering. Colleagues rely on him for elegant low-level solutions that make complex audio plumbing invisible in practice.
