Field notes from a builder · Medellín, CO
I build things on the internet and write down what I learn.

About
I'm a full-stack developer and AI automation consultant. I build custom AI agents, lead-generation systems and web apps with Convex, Next.js and n8n — and I've been writing code for 10+ years.
This site is where the professional and the personal overlap: what I'm shipping for clients, what I'm learning on my own, and life in Medellín.
