Summary
🤩
RockstarWilliam Durand is a Senior Staff Software Engineer with 15 years of experience and a long history of hands-on open source contributions, currently working on Firefox at Mozilla. He blends back-end expertise in PHP and Python with full-stack work across JavaScript and tooling, having authored and maintained libraries like Hateoas and BazingaJsTranslationBundle and contributed to widely used projects such as gecko-dev, web-ext, and addons-server. Will has a strong track record improving developer tools, CI/build processes, and integrations (notably enabling MV3 support and refining web-ext and addon tooling), while also contributing to ORM and pagination libraries like Propel and Pagerfanta. He enjoys mentoring and working in the open, routinely adding tests, documentation, and cross-project integrations that raise long-term maintainability. Based in the Clermont-Ferrand area, he brings a practical, systems-minded approach to shipping reliable features and squashing edge-case bugs across large codebases. A less obvious strength is his breadth: from low-level image-processing helpers to browser extension infrastructure, he moves comfortably between domain-specific problems and platform-scale engineering.
