I live and work in Buenos Aires.
I'm a product and design person who writes code. What I actually chase is the problem underneath the request: what the person on the other side is trying to do, and the shortest honest way to hand it to them. I'd rather ship one thing that holds up than four that pass. Quality is the last thing I'm willing to trade, and I've never seen it survive as a final pass over work that was built without it.
Right now that happens at Obel, leading the team building Malbec Live, one of the products in the Malbec OS suite. I own what enters the product: I prioritise, set the scope, coordinate the developers and clear what's in their way, and take the product and technical decisions together rather than separately.
When I think about product, working, scaling and performing are the floor, not the point. It also has to be beautiful. I mean that plainly: beautiful is a requirement sitting next to the others, not a coat of paint over them. It's the one that gets dropped first when something has to give, and I don't work well anywhere it isn't a priority.
You can find me on GitHub, X and LinkedIn, or reach me via email.
