At Movilidad Technologies, I built and maintained features for Buggy’s ride-hailing platform, from Node.js and Express APIs to React dashboards. I developed real-time driver tracking with sub-two-second latency and integrated a production OpenAI feature.
I also designed PostgreSQL and MongoDB schemas for live records and implemented authentication and access control. On WalletX, I independently built a peer-to-peer payments app with Google OAuth and QR-code payment flows; my work cut transaction processing time by 40%.
