Rockstar🎓
Top SchoolJF Bastien is a VP-level software platform leader with 13+ years building compiler-driven, safety- and security-focused platforms at the hardware/software boundary. He has driven production compiler and WebAssembly work at Google and Apple, led Toyota’s safety-critical software and Rust adoption as a Distinguished Engineer, and now crafts platforms that let code directly control physical systems. A chair of the C++ Language Evolution Working Group and former WebAssembly community lead, he blends standards leadership with deep backend engineering—LLVM/Clang, libc++, and WebAssembly toolchains feature prominently in his open-source contributions. His uncommon strength is marrying silicon-aware optimization with large-scale platform design and regulatory-grade security practices, enabling teams to ship safe, auditable systems in automotive and embedded domains.
