Tujyane website: one app to get a ride, book a trip and shop, shown on three phones — Tujyane, public site

Context

Tujyane puts rides, trip booking and shopping in one app. That means many tenants, real time drivers on a map, and money moving between riders, drivers and merchants every minute.

Tujyane on a phone — The same site on a 390 px phone screen.

What I built

01The multi tenant booking ecosystem: real time data flows, geofenced routing and event loops across services.
02A transactional wallet engine with an automatic payment ledger.
03WebSocket geocoding updates and notification gateways for SMS, email and push.
04PostGIS and PostgreSQL query and index tuning for location lookups.
