Jared Hirsch is a front-end engineer with 14 years of experience focused on Firefox Desktop UI and user-facing features, based in the Los Angeles area. He has shipped improvements across core Firefox projects—helping shape profile management, Accounts (FxA), and the Firefox Screenshots extension—while also contributing back-end work on authentication and subscriptions. Jared blends a physics-trained analytical approach with practical front-end craftsmanship, often tackling both UI polish and underlying logic (including telemetry and i18n). He’s comfortable across the stack, from JavaScript UX details to server-side auth flows, and tends to surface subtle usability and accessibility fixes like high-contrast rendering and clearer onboarding. An active open-source contributor, he continues to maintain Mozilla work on GitHub while migrating personal projects to Codeberg.
