Rockstar🎓
Top SchoolLuca Niccolini is a seasoned software engineer with 13 years of experience building and stabilizing low-level networking and infrastructure software, currently based in San Francisco and working at Meta since 2015. He blends backend development and DevOps expertise, contributing to high-profile open-source projects like Facebook's proxygen, folly, mvfst and fboss, with a focus on HTTP/3/QUIC reliability and CI/build systems. Luca repeatedly modernized and hardened build pipelines—migrating autoconf to CMake, fixing CI failures across multiple repos, and streamlining cross-repo dependencies—which significantly improved developer velocity and release reliability. His background includes research and systems work from Intel, Riverbed, and a Ph.D. stint, giving him a strong foundation in protocols and distributed systems. Notably, he pairs protocol-level fixes (datagram and error handling in QUIC/HQ) with pragmatic automation changes, showing an unusual fluency across both runtime behavior and the toolchains that deliver it.
