About

Professional summary

I am a Junior Full Stack Developer with a strong backend focus on Node.js, TypeScript, PostgreSQL, and explicit SQL. I completed the Henry Full Stack Developer bootcamp and am currently pursuing a Programming Technician degree at UTN.

I have built and deployed a multi-user expense-control PWA end to end, including data modeling, a REST API, integration tests, Docker, CI/CD, authentication, and a Telegram bot. I prioritize maintainable APIs, reliable database design, and practical testing against real PostgreSQL instances.

I also contributed to the backend of a multi-currency digital wallet in a four-person team. I designed database structures and REST endpoints that supported ARS, USD, EUR, and BTC operations, integrated AWS SES email delivery, aligned API contracts with the frontend team, and deployed the application on Railway.

As a freelance frontend developer, I work on a mobile application for healthcare clinics using React and Capacitor. I integrate Supabase Auth, Firebase Cloud Messaging push notifications, and client REST APIs while collaborating through Git feature branches, pull requests, and feature documentation.

I am comfortable with Docker, GitHub Actions, cloud deployment platforms, automated testing, and AI API integrations. I am a native Spanish speaker and have C2-level English proficiency according to EF SET.
