PRJ_01Mobile app · ML · scraping
Auction triage with computer vision
Mobile app (Android/iOS) that aggregates vehicle auctions from several auction houses and ranks opportunities. A scraper collects the lots, an OCR + NLP pipeline extracts risks from the PDF notices, and a computer-vision microservice (CLIP, zero-shot, no GPU) classifies damage in the vehicle photos. The scoring engine combines market (FIPE) price, risk and potential margin. Built for low operating cost, with no paid AI APIs.
My roleSolo, end to end: Laravel API, Playwright scraper, OCR and computer-vision pipelines, scoring engine, React Native app and CI/CD with automated deploy.
