Discovery & Architecture
We define scope, decisions, risks, and integrations before writing code.
David Muñoz · Estoy Programando
I build AI systems and teach how to build them.
YouTube is the hub: there I document apps, automations, bots, AI, architecture, security, and infrastructure. I also work with businesses, teams, and founders needing to transform an idea or process into a working system.

About me
The mix behind Estoy Programando.
I'm David Muñoz: systems and computer engineer, with a postgraduate degree in software development and over 15 years of experience. I design products, automations, and AI systems starting from real problems, taking them through architecture, deployment, and operation.
I am also a farmer, karateka, and father — not necessarily in that order. That combination feeds directly into what I build: discipline to practice, judgment to choose tools, an obsession with controlling infrastructure, and a passion for explaining what I learn without hiding the process.
