Summary
🤩
RockstarGuy Lewin is a software engineer with 17 years of experience building high-scale, security-focused infrastructure and distributed systems, currently at Meta. He has led large engineering efforts and technical strategy at Microsoft—owning long-term architecture, cross-team integrations, and novel proofs-of-concept like a remote browser isolation system—and commanded engineering organizations in the Israel Defense Forces. Hands-on strengths include systems programming, TLS/authentication, and networking (notably contributing TLS and auth features, RPCs, and TCP mux support to the popular open-source frp reverse-proxy project). Comfortable shifting between deep technical work and leadership, he routinely translates customer and compliance requirements (GDPR, BCDR) into resilient designs. Colleagues rely on him for pragmatic decision-making, rigorous error handling, and turning experimental POCs into production-ready products.
