About

01 — about

I'm a fullstack software developer based in Huila, Colombia, with around three years of experience and a foundation —uncommon at my level— in infrastructure and DevSecOps. My foundation of years is backend with Java (Spring Boot) and microservices architecture; today, day to day, I work with .NET Core.

I started as a junior developer at LianBPO, and it was at MetrixAL, over nearly two years, where I built most of what I know: microservices, sovereign CI/CD, containers, cloud deployments and observability, growing to technically lead projects. Today, as a fullstack developer at Transportes del Huila, I apply that knowledge developing and maintaining systems.

I don't (yet) hold an architect title, but I think and work like one: I prioritize design, good practices and a systems view over the rushed fix. I use AI as an amplifier, keeping judgment and decisions on my side.

I'm studying Software Engineering (5th semester) at Politécnico Grancolombiano and I'm a Technologist in Software Analysis and Development.
