About

I build products and the teams that ship them. Fifteen years in, I still write code every week — lately that means AI copilots on the Claude API. At Mobile Premier League (90M+ users), I was promoted three times — IC → EM → Senior EM — and led a 12-person cross-functional team through the work that moved numbers: React Server Components that cut p90 load time 43%, a CDN migration that took infra cost down 67%, and a server-authoritative multiplayer engine that dropped fraud ~40%. I own the full stack, from a Node/GraphQL BFF layer to the React/Next.js platform on top of it. More recently I've gone deep on AI engineering. I built Playbook, an operations copilot in TypeScript — a RAG pipeline with tool use, multi-step agentic workflows, a custom MCP server, an evals harness, and per-call cost instrumentation. I'm looking for a Senior EM or hands-on IC+EM role where the manager is still expected to write code and own architecture. Open to relocation. Reach me at safihamidi@gmail.com.
