Seventeen projects. Four of them are mine
The first four I built for myself. I designed them, wrote the code, set the price and shipped them. The rest is client work, which is most of the job and almost none of the credit. Every project here has a number attached to it, because design you cannot measure is decoration.

Sixteen years, and most of it under someone else's name
HP Labs in Palo Alto. A perfect K score at HP Costa Rica, awarded to one person a year. TripInsiders, best new app in the Hong Kong App Store and second of sixty startups at Rise. Teaching web design at Universidad Nacional de Costa Rica. Winner of the Global Voice Skill Competition in 2019. Most client work never carries the designer's name, which is the job, but it is worth saying out loud that the list above is a selection and not the total.
