Selected projects

Software I built that is running in the real world: desktop tools used by restaurants across Uruguay, integrations that move live orders, a server monitor born from a problem at work and a full stack web app with Next.js and Node.js. Each one has its own page with the problem, the decisions and how it turned out.

experiences.

Frontend

I focus on building interfaces that feel fast, clear, and easy to use. For me, frontend is not just about how things look, but how they behave making sure every interaction is smooth, responsive, and actually useful for the user.
