01.About Me
I'm a Full Stack Engineer with 5+ years of experience building web and mobile products with React, React Native, Next.js, Node.js, NestJS and TypeScript. I graduated as a Systems Engineer in 2023 from Universidad Tecnológica Nacional, which strengthened my foundations in software design and systems thinking.
Most of my career has been in startup environments, where I had the opportunity to work closely with the product, take ownership of important features, and think not just about implementation but also about architecture, performance and long-term maintainability.
I've worked in industries like EdTech, tourism and fintech, building products used by real customers and solving real problems. I enjoy working in complex flows, turning unclear requirements into solid solutions, and helping teams make technical decisions with product impact in mind.

Let's Talk
I'm currently open to new opportunities in Buenos Aires or remote. If you're building a product where engineers are expected to think deeply, move fast and generate real impact, we'll probably get along.
