C++ libraries and systems for building distributed infrastructure and services at Facebook/Meta scale. The cluster spans networking (Wangle, MVFST), monitoring (fb303), service mesh (OpenR), and language runtimes (HHVM/Hack), representing a cohesive ecosystem of foundational tools developed by Meta for high-performance, production-grade systems. These projects share common patterns around async I/O, observability, and the company's internal engineering practices.
