About

Simón Marín Giraldo

Background

I am a software engineer in Medellín, Colombia. I work on backend systems, machine-learning infrastructure and the internal tools that keep engineering teams moving.

The thread through my work is consequence. I spent six months in Zürich building a functional-safety demonstrator, where the governing assumption is that a failed component cannot be trusted to report its own failure. Before that I worked on SIATA, the environmental early-warning system for Medellín and the Valle de Aburrá. At MercadoLibre I took credit models from notebooks into production. Today I build internal tooling for the logistics team at Bold.

I studied Computer Science at Universidad EAFIT, where I was a Teaching Assistant for Data Structures & Algorithms. I have since returned as a mentor for final-semester students during their internships, which is one of the more rewarding things I do.

Day to day I build with agentic tooling rather than around it. I write skills, agents and hooks in Claude Code, and use it for technical design as much as for implementation. It has become part of how I work, not a novelty bolted onto it.

Away from the keyboard

I am a tinkerer by disposition. Drones are the current preoccupation. The flying is the excuse; what actually holds my attention is the stack underneath, which is the same set of problems I work on professionally wearing a much more interesting hat: sensors that lie, control loops with no room for latency, and telemetry that has to make it back to the ground.

The rest of it: travelling, hiking, and mentoring engineers who are earlier on the path than I am. My six months in Switzerland are still the clearest case of those interests colliding usefully.
