About me

Since Dec 2023

Working uninterruptedly as a Software Engineer

I'm a Software Engineer based in Medellín, Colombia, with a passion for building robust, scalable systems. Throughout my career, I've had the opportunity to lead technical projects from conception to deployment, working with diverse clients and challenging requirements.

I thrive in environments where I can architect solutions that make a real impact. Whether it's designing cloud infrastructure on GCP, building performant web applications with Next.js, or crafting efficient backend services with Go and NestJS, I bring a meticulous approach to every project.

Currently seeking remote opportunities with international teams where I can contribute my expertise in full-stack development and cloud architecture while continuing to grow as an engineer.
