10 PRINT "MEDELLÍN, COLOMBIA · IT SINCE 1988"
From Tandy CoCo BASIC to Agentic AI: Software, Data, Games, Cloud Infrastructure.
I have worked in IT since 1988. I retired in 2014, and in 2022 machine learning and AI brought me back. Now I spend my retirement playing and creating games and building with ML and AI. Retirement doesn't stop me from giving time, attention and effort to an interesting challenge.
What I work on
Data and analytics
Python, Streamlit and pandas tools for engineering and operations, from cleaning raw readings to models.
AI agents
Multi-agent workflows, agent skills and spec-driven development, with human approval for anything public or irreversible.
Cloud infrastructure
Google Cloud and my own Linux servers: Docker, systemd services, virtualization and automated backups.
Featured projects
Recent work since 2022.
Automation · 2026
Automated digital service desk
MVP selected as finalist in the Tienda Registrada 2026 challenge. An n8n workflow of about 60 nodes validates and audits point-of-sale backups with a local LLM and feeds a live IT dashboard.
