Six production and hackathon systems built from real constraints — from transport aggregation and field-level document encryption to voice AI for rural healthcare and weather-adaptive traffic models.
Unified ride aggregation platform combining five transport services — buses, cabs, metro, autos, and mixed routes — with real-road routing, booking history, and a FastAPI + PostgreSQL backend. Built to solve transport fragmentation in Indian cities.
