Summary
🤩
Rockstar🎓
Top SchoolSubodh Iyengar is a Principal Engineer in Palo Alto with 14 years building high-performance, secure networking software, currently leading Applied Privacy Technology at Meta. He previously led Meta’s QUIC transport and Transport Security teams, contributing to production-grade implementations and performance tuning between GPUs and network stacks. A seasoned C++ systems engineer, his open-source work includes substantive security and performance improvements to high-profile projects like mvfst (QUIC), folly, fizz, and proxygen. He brings deep TLS/SSL expertise—implementing session ticket rotation, client auth, and OpenSSL hardening—alongside pragmatic build and refactor work that reduces attack surface and improves efficiency. Collected from Stanford (MS CS) research in security and a background in scalable systems, he pairs academic rigor with production impact. An interesting detail: beyond protocol fixes he often targets nuanced state-machine and stream-accounting issues that measurably improve reliability under load.
