Summary
👤
Senior🎓
Top SchoolJavier Maestro is a Principal Engineer based in London with two decades of hands-on experience building and operating large-scale distributed systems, most recently architecting Monogres — a reproducible, Bazel-driven PostgreSQL distribution — and open-sourcing tooling used beyond his project. He has a strong track record at Facebook leading Production Engineering teams across monitoring, events, and data transport, where he delivered capacity tooling, decoupled pipeline designs, and major reliability operations for systems serving petabytes and billions of events. A pragmatic technical lead and founder, he blends systems-level engineering, reproducible build engineering, and operational rigor with deep experience in capacity planning and incident response. Javier is also an active open-source contributor (notably improving the Facepy library and upstreaming PostgreSQL reproducibility patches), reflecting a focus on code quality, maintainability and reproducibility that often yields tools adopted outside their original scope.
