About me

I was born in 1987, Buenos Aires - Argentina.
I’ve started programming at 12, in Visual Basic 6, as a hobby. Now, I’m a fullstack software developer with more than 11 years of professional experience in many languages.

I’m very passionated for UI/UX design, mobile and front-end development; as well as backend. And I love build things that others find useful .

Things enter through the eyes first.

Since 2011 to this days, I’m proud to be part of the main product of this company.
