George Lester
Software Engineer at Epic Games
Bellevue, Washington, United States
Summary
🤩
RockstarGeorge Lester is a software engineer with 12 years of experience building high-throughput, production-grade backend systems, currently driving engineering at Epic Games in Bellevue. He has designed architectures that handled millions of live-streaming transactions per second and built fault-intolerant systems for broadcast customers where uptime and correctness carried legal risk. Past roles at Comcast, Microsoft, and thePlatform spotlight his full lifecycle ownership—from architecture through deployment—of cloud-native, containerized, and monitoring systems. He’s an active open-source contributor with deep low-level expertise in package management and expression evaluation (notably adding APK support to fpm and core parsing to govaluate). George prefers tackling hard problems in ways that make them easy later, and often surfaces hidden requirements early to avoid costly rework. Practical, detail-oriented, and mentorship-minded, he bridges ops and engineering to ship resilient systems at scale.
