// about

Why I do this.

I'm a systems engineer from the mighty Universidad de Córdoba 💚.

Few things are as satisfying as seeing what we build end up making people's lives easier.

I enjoy working where engineering meets product. I like understanding the business I lend my technical knowledge to, because grasping the "why" behind every decision is part of my work philosophy.

To me, writing code is about much more than shipping features: it means keeping technical debt in check and building solutions my future self —or any other developer— can understand, maintain, and evolve for years.

Human First, Powered by AI ✅

// experience

Code in production.

I work on a system in real use, where every technical decision has business consequences.
