A builder at heart.

I’m a developer based in Flores, Uruguay. I enjoy taking a product from its first sketch to something people can actually use — and understanding every layer along the way.

Building Moka taught me to connect engineering with product decisions. Today, at Ahí Va, I work on mobile migration, backend evolution and technical direction. My personal experiments give me another way to keep learning.
