What I'm looking for

I’m looking for a role where I can own end-to-end mobile or full-stack delivery—integrating cloud data, building reliable dashboards, and applying AI thoughtfully—while collaborating with cross-functional stakeholders to ship measurable impact.

I’m a Computer Engineer building and maintaining LitoralBikes, an Android application in active commercial production, with full end-to-end ownership from architecture to development. I integrated Firebase (Firestore, Auth, Storage) and the Gemini API, delivering real business value through an AI assistant, real-time multi-role access, and ongoing production maintenance for 4 years.

Currently, I co-develop a digital health system for a public healthcare center (CESFAM El Quisco). I lead requirements gathering with clinical staff and translate non-technical needs into functional specifications, while building the frontend for the medical platform and patient mobile experience.

I thrive at the intersection of mobile, cloud integration, and data—turning operational signals into dashboards and decision-ready KPIs. With strengths across Ionic/Angular/Capacitor, APIs, Google Cloud services, and analytics, I’m motivated by building reliable systems that users trust.
