About

Designing where complexity meets users — for 9+ years.

Born in Bogotá, based in Medellín. Spent the last decade designing on top of platforms most designers never touch — Salesforce, SAP, legacy enterprise software — while also building consumer-facing products in fintech and retail. The thread across both: clarity beats decoration, especially when stakes are high.

I work tool-agnostic on Figma and modern design tooling, collaborate fluently with engineers on GitHub and Jira, and integrate AI tools (Claude Code, Figma Make, Cursor) into ideation and rapid prototyping — to compress the distance between concept and validated direction.

The shift in my workflow over the last two years has been significant. AI didn't replace design judgment — it accelerated everything around it. The prototype IS the wireframe now. Validation happens on day one. What used to take weeks of static mockups now happens in playable code with a PM in the room.

I take projects where the design problem isn't cosmetic — where the architecture matters more than the visuals, and where the work is to extract the right system from a tangle of constraints. Legacy modernization, design systems for B2B platforms, end-to-end product design.
