Florent Castelli is a seasoned C++ software engineer with 17 years of experience building and hardening tooling, build systems, and build-related services across large-scale projects. Based in Stockholm, he has driven build and CI improvements at Spotify and contributed to WebRTC in Chrome at Google, implementing RTCPeerConnection APIs and network throttling for Meet. He’s an active open-source contributor who has extended Boost integration for CMake, improved emulator audio and cross-platform builds (PPSSPP, Dolphin), and added WebRTC tests in the authoritative web-platform-tests suite. Comfortable across DevOps, backend and low-level systems, Florent blends deep build-system expertise (CMake, caching, CI fleets) with protocol-level work (SCTP, WebRTC data channels). Pragmatic and detail-oriented, he often surfaces non-obvious reliability gains by optimizing build pipelines and catching subtle cross-platform issues early.
