About
I'm a Computer Engineer (Rafael Urdaneta University) and a Full-Stack & Mobile developer based in Maracaibo. In ALKOSTO's Innovation division I build consumer and operational apps with React Native, Expo, React/Next.js, TypeScript, Node.js and Go, including real-time systems, geolocation and push notifications.
I care about shipping reliable, maintainable software: REST APIs, JWT/RBAC, PostgreSQL and MySQL, Docker, CI/CD and Sentry. I also study cybersecurity.
