Profile · LB-2022

I’m a backend developer and co-founder of Gentle Tech in Buenos Aires. I spend most of my time working on security systems and authentication workflows.

I’m particularly interested in problem-solving. Outside of work, I usually work on a few projects, such as a recipe app or a fully offline financial manager, mainly because I enjoy learning as I build.
