Profile Overview

I began my academic journey studying Translation while also dedicating myself to professional sports. However, I have always been drawn to engineering roles. Over time, I transitioned into Computer Science and pursued formal studies in Information Technology at Universidad de Palermo, complementing my education with continuous self-directed learning and hands-on experience.

I am also passionate about martial arts, having trained in Brazilian Jiu-Jitsu for nearly ten years. This discipline has shaped my mindset, instilling perseverance, consistency, and long-term focus.

With nearly four years of experience in technology-related roles, I have developed strong expertise in Python, AWS, Node.js, AI, LLMs, SQL, Linux, and Flutter, among other technologies.

A collaborative team player with professional-level English, I excel at identifying patterns and building robust solutions that drive real business value.
