Hi! I'm Iván.

If you've ever used Mercado Libre, you've already run code I wrote and a ton more I reviewed. Beyond being an engineer there, I'm the tech partner for businesses that want to scale without the headaches. I turn your ideas into solid, custom-built platforms, so you can focus 100% on selling and growing your company.

About Me

I built every corner of this site myself, because I think a portfolio should show how someone builds instead of just saying it. Everything here, from the library to the little music game, is what I make when nobody's paying me. Imagine what happens when someone is.
