I built a real-time vehicle tracking system for 800+ public and private vehicles with separate Admin and User panels. The system includes GPS tracking, geofence alerts, vehicle reports, and staff management using Socket.io for live updates. I also developed College Bus Track for students to track route vehicles and LMC Garbage Alert to notify users when garbage trucks are nearby. Tech stack: React.js, Tailwind CSS, Shadcn, TypeScript, Redux, React Query, React Table, and Socket.io.
