Quick Start Guide
Pau De Aragón
Runs best on clear constraints, a good problem, and freshly ground coffee.
- Overview
- Principal Product Designer in Mexico City. I build the shared language between design and engineering, and I've spent seven years making sure it survives contact with real organizations. W3C-certified in Web Accessibility, because we're all temporarily abled.
- Core Capabilities
- Systems 0→1 that stick across organizations that weren't fully on board at the start. I think in structures, document obsessively, and translate between design, engineering, and leadership without taking sides.
Bonus: three audits in one session that would've taken a team three weeks. - Optimal Conditions
- Clear ownership. Engineering as a co-builder from day one. Problems larger than one job description. Enough autonomy to move before consensus forms.
- Running In The Background
- Learning Japanese. Planning the next trip to Japan. Self-taught on guitar, piano, and bass. Video games collected since elementary school, good training for systems thinking.
AI lets me build things I couldn't build alone. Here's some of them.

The mini Aero dashboard
A working three-panel tool: system health, a token and component explorer, and an Ask Aero interface wired to the Anthropic API. Most designers talk about AI and systems. This is what it looks like when you build it.

Translates design feedback into token decisions. Type what a designer says, get what an engineer needs.
