TakeALift — Carpooling & P2P Vehicle Rental

I built a carpooling and P2P vehicle rental platform with real-time driver dispatch — Redis GEO proximity search, distributed locking to prevent double-dispatch, a NATS event bus, and full AWS infrastructure-as-code across native Android, Flutter, and a TypeScript backend.

The Honest Part

I built all 19 commits in a 1.5-hour window — I'm being upfront that this reads as AI-scaffolded rather than iteratively built. I also need to fix my README: it claims 'unit tests for all business logic' and 'multi-cloud ready,' and neither holds up yet (my tests only cover auth + basic API flows; my Terraform is AWS-only).

Highlights

Redis GEO proximity search for real-time driver dispatch with distributed locking to prevent double-dispatch
NATS event bus for async communication across services
Full AWS infrastructure-as-code via Terraform
Three clients: native Android, Flutter, and TypeScript backend
