Overview
LessGo lets SJSU drivers post scheduled trips and riders book seats that fit their schedule, with every user verified against a valid SJSU student ID before they can participate.
Under the hood it's nine microservices — auth, trips, bookings, payments, notifications, cost calculation, and two ML services — behind a single API gateway, talking to a PostGIS-backed Postgres database on Supabase.
What I built
01
ML-based route-compatibility matching (RShareForm embeddings) ranks trips by how well routes actually align, not just pickup proximity.
02
Dynamic fare engine handling detour surcharges and multi-rider discounts, with a T-1h freeze that locks in and redistributes savings-pool discounts across confirmed riders.
03
Real-time safety service monitoring route deviation and speed anomalies mid-trip, plus live chat, location tracking, and Stripe payments captured only on trip completion.
