01 — Philosophy
Beyond
the logic.
“Writing the code is the easy part. The hard part is leaving it so whoever comes next understands why you did it that way.”
I've spent more than thirteen years building software from Guatemala for teams in other countries. I've worked at every layer: the schema, the API that exposes it, the interface people actually use. None of them forgives neglect, and over the years I learned to give all of them the same respect.
Global Impact
Remote work with teams across time zones. Python, TypeScript, React, Node.js, Rails.
Human Side
Guitar and percussion, some bass and ukulele. BMX, and a cat who demands more than he gives. I write clearly and ask before assuming.

Excellent work. I want to highlight his creativity, his guidance throughout the entire process, and the transparency with which he works. He shares all the information, allowing you to truly own your digital products — without depending on third parties or having your information held hostage. Highly recommended.

Let's build
something that
I take on few projects at a time. I work best with people who know where they want to go but not yet where to start: architecture, full builds, and a digital presence that starts out right. When it ships, the code and the access are yours.
