Summary
👤
Senior🎓
Top SchoolMichael Yu is a versatile software engineer with 12 years of experience building scalable systems and performance-critical components across consumer tech and games, currently at Facebook in Mountain View. He brings deep low-level expertise—demonstrated by contributions to the high-profile RPCS3 PlayStation 3 emulator where he improved virtual memory handling, fixed out-of-bounds access, and optimized PNG decoding—alongside a strong full-stack record from services to front-end. His background spans C/C++ systems, game prototyping in Unreal/Unity, Python/Go tooling, and large-scale cloud services (AWS, Docker, Grafana), enabling him to bridge game engine R&D and production service reliability. He has a track record of refactoring legacy auth and shipping cross-platform fixes at scale, automating observability, and building ML-ready tooling for security and AV contexts. Pragmatic and curious, he often surfaces subtle bugs via careful binary-search debugging and performance-minded memory work that yield disproportionate reliability gains.
