March 2025: Delivered cross-repo features to improve security, usability, and reliability. Implemented macOS FSEvents integration for native file change notifications in the petfinder project, added profile picture management with device media library integration and Supabase storage, and refactored authentication to use Supabase signInWithPassword/signUp with a groundwork authUtil.js. Stabilized development environment by adding a gitignore and resolving dependency issues. In the tracklist repo, added Google Sign-In with Firebase, enhanced profile with username editing, and cleaned build tooling and Firebase config to ensure reliable builds. Overall impact includes faster onboarding and user flows, stronger authentication, and reduced merge-conflict and build instability. Technologies demonstrated include Node.js, Expo, FSEvents, Supabase, Firebase, Google Sign-In, device media library integration, yarn/babel tooling, and Git hygiene.

February 2025: Delivered foundational backend and UI scaffolding across two projects, establishing a scalable, secure, and maintainable base for future features. Implemented Firebase backend with authentication persistence (AsyncStorage), Firestore data, and Storage for the Tracklist app; established core app scaffolding, repo hygiene, dependency stability, and navigation using Expo Router. Added a user profile management page and centralized authentication error handling for PetFinder. These efforts improve data security, offline capabilities, UX consistency, and developer efficiency, enabling faster delivery of business value in subsequent sprints.
