Summary

Rockstar🎓
Top SchoolAlexandre Poirot is a Staff Browser Software Engineer with 15 years’ experience building and debugging web platforms, browser internals, and cross-platform integrations from Paris. He has deep expertise in core web technologies (HTML, JavaScript, CSS) and a proven track record connecting web layers to native code across Android, iOS and desktop (Java, Objective‑C, C++). At Mozilla he contributed to addons, WebIDE, devtools and Firefox OS projects, and earlier led R&D at Yoono where he rebuilt cookie handling in JS and shipped multi‑account, cross‑platform apps and developer tooling. Known for hunting memory leaks and tracking JavaScript performance issues, he combines hands‑on low‑level debugging with front‑end UX fixes—evidenced by UI bugfixes for the prominent Gaia (Firefox OS) repo. He brings a pragmatic “Swiss Army knife” approach: comfortable switching frameworks, languages and layers to rapidly diagnose and ship robust solutions.
