A Bit About Me

I partner with founders and teams to build and launch AI products — from shaping the idea and narrowing scope to shipping the first version. I’m also building Casamo, an AI tool that helps remote workers find good long-term stays.

Based in Buenos Aires, working US hours. US clients contract with me through HC Studio, my LLC.

Point of View

In the age of AI, taste gets a lot of attention. But the harder skill is deciding what’s actually worth building — and then following through. Implementation is getting easier. Clear judgment and execution are becoming rarer.
