Rockstar🎓
Top SchoolMaxim Fedorov is a Technical Director based in Mountain View with nine years of experience building highly reliable, scalable BEAM-based infrastructure. As WhatsApp’s Core Infrastructure Lead he helped scale the service from 1B to 2.5B users, reduced server footprint by 25%, redesigned service discovery and productionized TLS cluster connectivity while shipping tools like power_shell and erlperf. An Erlang ambassador and founding board member of the Erlang Ecosystem Foundation, he contributes upstream to erlang/otp and rebar3—work that ranges from preventing emulator crashes and improving PKCS8 handling to adding parallel compilation and smarter dependency verification. Now at Roblox, he combines low-level runtime expertise and build-system mastery with a proven ability to turn internal forks into upstream contributions and modernize developer workflows for massive distributed systems.
