I led development of a production-ready POS and inventory management platform for the automotive retail sector, building its Angular frontend and integrating RESTful APIs with Node.js and Express. I also managed MongoDB Atlas data persistence and production deployments using Vercel and Render.

I'm developing Recauda, a mobile app for field donation tracking, with React Native and Expo backed by a Node.js API and PostgreSQL. I implemented offline-first session management for zero-connectivity environments and OTA updates through expo-updates.
