Mapbox map with clustered markers (Turf/GeoJSON) and real-time states: available, matched and selected.

ChargeShare.
EV Charger Sharing
A mobile marketplace where EV drivers find shared chargers, match with hosts and book available hours. The backend checks host availability and prevents double bookings, while Socket.IO supports chat between matched users. Stripe Connect handles payments and host payouts, with webhooks reconciling payment status and a web dashboard for booking and revenue analytics.
My role
As Co-Founder CTO, I architected and built the React Native app, Fastify backend, PostgreSQL database and web admin dashboard, modelling the host and renter journey from discovery and matching to booking and payment.
