Rockstar🎓
Top SchoolAnton Korobeynikov is a Principal Compiler Engineer and Research Scientist with 19 years of experience specializing in compiler internals, performance engineering, and memory allocation. Based in Greater Vancouver, he combines academic depth—a PhD in Statistical Modeling—with extensive hands-on work on industry-defining projects like LLVM/Clang and the Swift compiler, contributing to SIL optimizations and autodiff code generation. He led technical development of the SPAdes genome assembler and has improved low-level allocator performance in Microsoft’s mimalloc, showing a rare blend of systems, compiler, and computational biology expertise. A long-time LLVM Foundation contributor and board member, he has shaped tooling, portability, and testing practices across the ecosystem and chaired EuroLLVM program committees. Known for pragmatic refactoring and race-condition fixes, Anton brings rigor from academia to production-grade compiler and performance engineering.
