Worked on feature development for both the uoftblueprint/brampton-tennis-queue and mozilla-mobile/firefox-ios repositories, focusing on queue management and iOS download user experience. Enhanced the leave queue and nickname management flows by ensuring consistent state transitions, dynamic data updates, and preservation of user edits, while also cleaning the codebase for maintainability. On Firefox iOS, implemented a Dynamic Island Live Activity UI for the download manager, providing users with real-time progress feedback. Applied skills in JavaScript, Swift, and API development, and maintained disciplined, well-documented commits. Prioritized reliable state handling, user feedback, and robust CI processes throughout the month’s engineering work.
