RidePals

Community carpooling platform for neighborhoods, campuses and offices: "neighborhood BlaBlaCar with weekly recurrence and trust-based reputation". Drivers publish one-off or recurring rides (weekdays + time + end date) with seats, price per seat and coordinates; passengers search by origin/destination/date sorted by proximity (haversine) with filters for seats, eco vehicles and minimum rating; they book seats with atomic capacity control (no overselling under concurrency) and the driver confirms or rejects. Completing an occurrence unlocks cross reviews 1–5 (one per booking, duplicates rejected) that feed reputation. Dashboard with rides given/taken, km and €/CO₂ saved, average rating, upcoming rides and monthly series; favorite routes for one-click search; per-ride messaging between driver and passenger. Recurrence expansion with generate_series, haversine in SQL, JSONB for the recurrence rule. "Open Road" UI (highway green, signal orange, night asphalt). Login with username or email, persistent JWT. Angular 22 + NestJS 11 + SQLite.
