Hola, soy Alberto — ingeniería móvil en Santiago de Chile.
Escribo sobre lo que me hubiera gustado leer estabilizando una app a las 2am.
I'm writing
posts, articles, and the blog, all in one threadContext-First Development (CFD): A Methodology for AI-Assisted CLI Development
A methodology for structuring repositories so AI coding agents work with persistent, accurate, explicit context — instead of losing it every session.

Sobre mí
I studied in Havana, and my first serious product was a messaging app used by more than two million Cubans—despite the limited bandwidth available at the time. Since 2020, I’ve been living in Santiago, Chile; along the way, I’ve worked in banking and fintech in Chile, Peru, Brazil, and Spain, almost always on the same type of project: a live app that needed to be taken more seriously.
What interests me about mobile isn't glamorous: stability, security, and the little details that determine whether a user will open the app tomorrow. That's what I write about.
