My Contribution
What I built
Designed and wired backend API routes for auth, events, photos, and user sessions using Express and MongoDB.
Built the data models and schemas, then kept them in sync with the frontend as requirements changed mid-project.
Contributed shared React Native components (cards, forms, layout) so screens stayed visually consistent across the team.
Migrated key storage to Firebase when our deployment needs shifted later in the quarter.
