#About

I'm a frontend engineer with more than six years of professional experience building complex web applications for startups and international companies.

I specialize in React, Next.js and TypeScript, with extensive experience developing dashboards, internal tools and SaaS products. Throughout my career I've worked on applications involving real-time updates, mapping solutions using Google Maps and OpenStreetMap, performance optimization, accessibility and scalable frontend architecture.

While frontend development is my primary expertise, I'm also comfortable extending features into the backend using NestJS, Express and PostgreSQL whenever a project requires end-to-end ownership.

I enjoy working closely with product teams, founders and engineers to deliver maintainable software that performs well in production. I'm currently available for remote contract work across Europe, the US and Argentina.
