Summary
🤩
Rockstar🎓
Top SchoolLuca Greco is a Senior Firefox Developer with 17 years of experience building web-rich clients and browser extensions from his base in Apulia, Italy. At Mozilla since 2015 he focuses on WebExtensions APIs and developer tools, contributing to foundational projects such as webextension-polyfill, web-ext, and the gecko-dev codebase. He combines front-end UI finesse (CSS and in-page toolbars) with full-stack work—porting popular devtools like Ember and Angular inspectors to Firefox and improving add-on linting and tooling. His open-source contributions show attention to testability and cross-browser compatibility, including substantial work on automated tests and refactors to modern async/await patterns. Less obvious: he has deep legacy-to-modern migration experience, having evolved XULRunner-era extensions and the Add-on SDK toward contemporary WebExtension models. This blend of hands-on coding, tooling, and migration expertise makes him adept at keeping browser ecosystems both innovative and maintainable.
