My Expertise
Areas where I excel and can help bring your ideas to life.
Mobile Development
Native Android and iOS (Kotlin, Swift) and cross-platform (Flutter, React Native) shipped to production.
Full Stack Development
End-to-end web in React and Node.js, plus the database layer that holds it together.
Cybersecurity
Bug hunting, penetration testing, and secure coding reviews on production systems.
DevOps & CI/CD
Pipelines, cloud infra, and the build/test/deploy loop that keeps releases boring.
Selected work
A handful of projects across mobile, web, and games. The full archive lives below.
BICOS
An Open Banking application developed during a hackathon hosted by TecBan (company responsible for Banco24Horas ATMs). The project won the competition by showing that users don't need to understand Open Banking to benefit from it.
CAM Covers
An application that transforms ordinary photos into professional-looking album covers, inspired by real music players.
React Native - Zendesk SDK
A wrapper for Zendesk SDK in React Native, making it easy to integrate customer support functionality into your mobile apps.
Stone World
A push box puzzle in pixel art: push rune stones onto an ancient altar, take keys from chests and open gates across 20 hand-made chambers.
