A Bit About Me

I work with founders and teams when the job is bigger than code alone: shape the product, narrow the first version, build the software, and get it launched. I'm also building Casamo, an AI-powered stay-decision tool for remote workers choosing a long-term stay.

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

Point of View

Everyone keeps saying taste is now the most important skill. I find that framing to be incomplete. It stops the question too early. Taste doesn't do much if you don't know what you want to build in the first place. AI has made implementation cheap. That shifts the bottleneck to something harder: being honest enough with yourself to pick the right problem and actually follow through.
