Summary
🤩
Rockstar🎓
Top SchoolJoseph Perez is a Rust software engineer with seven years of experience building high-performance distributed systems and language bindings from the ground up. Based in Île-de-France, he has led architecture and API redesigns at ZettaScale and Numberly, delivering production-grade Rust services that handle millions of messages per day with zero production bugs. He is a pragmatic performance optimizer—his proposals drove most of a 70% speedup at ZettaScale and he engineered a driver and MPSC channel innovations that improved ScyllaDB Rust driver performance by up to 50%. Equally comfortable across systems, bindings (Python, Kotlin, C/C++), and DevOps, he built tooling to validate API alignment across languages and automated performance testing. An active contributor to the scylla-rust-driver, he blends deep systems thinking with hands-on implementation to simplify ergonomics and squeeze out latency and resource gains.
