The Problem
Finding specific deals in Facebook buy/sell groups requires constantly refreshing feeds and manually scanning hundreds of posts. Good deals sell out within minutes, so speed is critical.
The Solution
Built a deal hunter agent that uses Playwright to monitor Facebook groups, Gemini Vision to analyze product photos and descriptions, and MongoDB to track seen listings. Sends instant notifications when items matching configurable criteria appear. Phases 1-2 complete with 131 tests passing.
