Alan Frindell
Software Engineer at Meta
Seattle, Washington, United States
Summary
🤩
Rockstar🎓
Top SchoolAlan Frindell is a seasoned software engineer with 13 years at Meta and a two-decade career focused on high-performance backend systems and networking protocols. He holds BS and MS degrees in Computer Science from Stanford and has deep hands-on experience implementing and hardening transport and HTTP stacks, notably contributing to Facebook projects such as fbthrift, folly, mvfst (QUIC), HHVM/Proxygen, and wangle. His work shows expertise in buffer management, HTTP/2 and HTTP/3 (QUIC) reliability, session/stream handling, and graceful connection shutdowns—areas that directly impact large-scale service robustness and performance. Comfortable across C++ system internals and API design, he’s improved core libraries and test infrastructure while preserving backward compatibility in critical code paths. Based in Seattle, he combines research-grade education with pragmatic production engineering honed at Meta and earlier systems-architecture and management roles. A less obvious strength is his pattern of making incremental, safety-minded refactors (e.g., detachability APIs and optional parameters) that reduce risk while enabling future evolution.

An implementation of the QUIC transport protocol.
Role in this project:Back-end Developer
Back-end DeveloperContributions:15 commits, 2 PRs, 1 push in 3 years 7 months
Contributions summary:Alan primarily contributed to the QUIC transport protocol implementation. Their work involved removing unnecessary includes, addressing specification changes (e.g., removing reset on reset), and splitting the stream state machine into send and receive components. The user also implemented helper functions for stream reset handling, updated related code, and fixed a couple of bugs within QuicTransportBase and QuicStreamAsyncTransport.
