About

Informatics engineer focused on full-stack development.

I'm an informatics engineer from Universidad Autónoma de Occidente and a full-stack developer. I work with React, Next.js and TypeScript on the frontend; Node.js, NestJS, Express and Python on the backend; and PostgreSQL, MongoDB and MySQL for data persistence. I also use Docker and cloud services to ship applications to production.

I'm currently pursuing a Master's in Artificial Intelligence and Data Science, where I build on my software development experience with the integration of models, agents and AI services.
