Multilingual Mandi Platform

I built a real-time marketplace connecting local vendors across language barriers, with a provider-chain translation fallback (Google → Microsoft → AWS → mock) and Redis-backed WebSocket negotiation.

The Honest Part

My "AI" price discovery and negotiation are rule-based heuristics on synthetic data, not ML — I'm describing that accurately rather than calling it "AI-powered." All 11 of my integration tests currently fail (db is not a function), and only my mock translation provider actually runs — I haven't wired in real API keys yet.
