TripPlanner
Problem
Trip planning was split across route math, map state, and privacy-sensitive storage, making it hard to ship one coherent planner.
Contributions
- Implemented A* route optimization for multi-stop trip planning with dynamic graph construction.
- Built a privacy-safe export flow with pseudonymization, consent gating, and audit logging.
- Created the Mapbox experience for route rendering, activity filtering, and saved-trip review.
Architecture
- React frontend → Express API → Firebase Firestore
- Mapbox GL renders routes, pins, and trip overlays
- Test coverage with Vitest validates privacy and routing logic
