I’m a Fullstack Software Developer with 2+ years of experience building web, mobile and desktop applications, specializing in React, React Native, Node.js and TypeScript.

My path started at Holberton School, where I built full-stack projects with React, Python (Flask) and MySQL and solved 100+ algorithm and data structure exercises. Since then I’ve worked on products across Colombia. At Betek, I built an on-demand services web app with React and Firebase and set up CI/CD pipelines. At Seguridad Penta / Bartik, I led UX/UI improvements across a suite of 5 web, mobile and desktop apps, designed the frontend architecture of 4 SaaS applications, and drove the migration of critical dependencies.

What makes me unique is that I combine solid engineering with a strong focus on user experience. I care about scalable architecture and clean REST API integration, but also about how the product feels to the people using it. I also work with AI-assisted development using Claude Code, which helps me ship faster without compromising quality. I’m used to remote, Agile (Scrum) workflows, and I’m looking for a team where I can keep growing while delivering real impact.
