Netherlands
Summary
🤩
Rockstar🎓
Top SchoolWillem Melching is a founder and security researcher with 13 years of embedded and automotive software experience, combining an MSc in Systems & Control from TU Delft with hands-on reverse engineering and penetration testing. He led controls and the openpilot team at comma.ai, bringing Linux and drive-by-wire support to production hardware and improving control robustness across hundreds of supported cars. Equally at home in firmware and backend, he has made substantial open-source contributions to projects like panda, openpilot and opendbc—adding safety tests, CI, and CAN tooling that directly raised system reliability. Today he runs I CAN Hack, specializing in automotive fault injection, side-channel attacks and bespoke training, while still tinkering with small hardware-software projects that bridge math, control theory and practical security. A pragmatic problem-solver, he often turns complex vehicle internals into repeatable test suites and defendable attack analyses.
