/ 01 — About

The human
behind the systems.

I'm a product designer from Barranquilla — now working as a design engineer. Twelve years from agencies to analytics platforms, cruise-line apps and national banking, most recently leading Andes, the design system behind Mercadolibre across eighteen countries.

What's kept me here isn't any single screen — it's the systems underneath. The tokens, the governance, the shared language that lets hundreds of designers and thousands of engineers ship as one product. I care about the unglamorous scaffolding that makes good design repeatable.

This past year I've gone AI-native — my day-to-day now runs on Claude Code, Cursor and Gemini. So I've stopped drawing a line between design and engineering: I prototype in code, ship real interfaces, and let the system and the AI carry the repetitive weight.
