Software Engineer at Facebook
Palo Alto, California, United States
Summary
👤
Senior🎓
Top SchoolKen Lim is a software engineer with 12 years of experience building full-stack web, mobile, and server systems, currently working at Facebook from Palo Alto. He favors frontend engineering—React and TypeScript—but ships across the stack and has driven measurable performance gains like reducing bundle sizes 4x and slashing page loads from ~9s to <500ms. At GIC he independently delivered an MVP real-time analytics platform used in production with sub-10s p99 query latency, and he has deep practical experience with caching, CQRS, and mobile NTLM integrations. A lifelong coder who started at 13, he blends strong engineering fundamentals (first-class honors in chemical engineering) with curiosity for newer tech—experimenting with Elixir, Kubernetes, and ReasonML. He’s equally comfortable optimizing low-level algorithms (A* pathfinding improvements in simulations) and crafting polished user interfaces, making him a pragmatic problem-solver who moves prototypes to production.
