About
I'm Juan David Calderón Ardila, a senior product designer and UX lead based in Prague.
Seven-plus years in B2B SaaS, on products where the interface carries a lot of complexity without making people feel it. Spanish and English.
The shape
A comb rather than a T. Broad across the craft, deep in three places, so I can size a problem, run the test and ship the front end.
- Growth & CRO UX
- Agentic & conversational AI
- Build fluency
The journey
Drawn to scale, because the engagements overlap.

What I believe
Education
A mosaic, and that's the point. First how images and stories get made, then how software gets built.
- Audiovisual and multimedia communications
- Media planning
- Software design
- Master's in new media, photography focus
- École 42
Outside work
PerfumeBlends macerate for months. Better patience training than any retro.
PhotographyWhere I started.
CeramicsThe only part of my life with no undo button.
Trip planningWell past the point of usefulness.
Small buildsA trip planner, a spec testing tool, automations for tasks that annoyed me twice.
Film and pop cultureOpinions held, happily contested.
And I write.
