/ about

Hi, how's it going? I'm Brahi, from Uruguay. I've always been curious, proactive, and energetic. Since I was a kid I liked learning new things, and at 12 — with a Pentium 2 the whole family used, and a CD of Visual Basic video tutorials — I started programming.

Years later I joined a volunteer program to teach robotics to children with special needs at Escuela Especial María Nila Larrosa, in Rocha.

That was a turning point: I discovered I didn't just enjoy learning — I had a huge passion for teaching, guiding, and leading, encouraging laughter, teamwork, and peer support.

After that, the rest is history…
