Summary
🤩
Rockstar🎓
Top SchoolMahmoud Mazouz is an R&D software engineer based in Greater Paris with nine years of experience focused on systems, programming languages, and distributed systems. He has a strong Rust pedigree—implementing SIMD-accelerated parsing at BNP Paribas CIB achieving 1–6 GB/s throughput and contributing fixes to the rust-lang compiler—and has optimized the Nickel configuration language at Tweag. Since late 2023 he’s been advancing the Eclipse Zenoh project at ZettaScale, working on routing, release automation, stress testing, RMW performance, and developer tooling like a record-and-replay system and interactive shell. Mahmoud combines low-level performance engineering with practical systems design and a taste for clean, efficient software—an ethos reflected in his GitHub contributions. He intends to grow into a systems architect role, bringing both implementation depth and a focus on observable, reliable infrastructure.
