Summary
👤
Senior🎓
Top SchoolHani Damlaj is a software engineer in Seattle with nine years of experience focused on transport and HTTP protocol engineering at Meta, where he contributes to high-profile open-source projects like mvfst (QUIC) and proxygen. He specializes in backend systems, performance tuning, and protocol correctness—fixing race conditions, adding datagram support, and improving congestion detection and handshake logic. Past internships at Facebook and Microsoft gave him full-stack and TCP/IP stack exposure, respectively, and he has a strong academic record from Concordia and McGill. Curious and hands-on, he maintains a habit of learning by digging into complex systems-level code and shipping practical fixes in production-grade C++.
