Fifteen years of iOS apps.
Newest first. As you scroll, the phone turns into the one each app shipped on, all the way back to an iPhone 3GS. Somewhere in the middle it becomes a print, from the years I spent taking photos instead of writing code.
2021 — now
Polarsteps
Staff Engineer · Plan pillar captain
I joined in January 2021 as the only iOS engineer. Five years later there are fourteen of us, the app is split into more than forty Swift packages, and I lead the Plan pillar. Nobody has been on the iOS team longer.
iOS engineers on the team I built

Swift packages, from one Xcode project
40+
Split the app into 40+ Swift packages. Fewer merge conflicts, teams shipping in parallel, and tests per module.
Built the iOS team, from just me to fourteen engineers.
Lead the Plan pillar, the part of the app where people plan their trips.
Was there while Polarsteps grew from 1M to 25M travellers. That one was the whole company.
Verneda en familia is a guide for a family week in the Val d’Aran: 18 walks with realistic driving times and a plan B for when little legs or the weather give up. Games is a set of puzzle games for ages 4 to 99. The first one, Moonsteps, has you building paths so two astronauts can meet. No ads, no tracking, no accounts.
An app that teaches you to order coffee like a local in Spain, Portugal, Italy and France: what each drink looks like, what goes in it, and how to ask for it. I built the iOS app on my own in SwiftUI; Rob Diaz did the design and the website.
In 2017 I quit my job and travelled for eight months: Nepal, Jordan, Chile, India, Australia, New Zealand and a few more. The photos turned into a small business with media kits for tourism brands, stories for Exposure, a print shop and two exhibitions in Madrid.
Lonely Planet Pathfinder in 2017 and 2018.
14 Exposure Staff Picks, and a few Behance gallery features.
Worked with Travellers Autobarn in New Zealand and tourism companies in Nepal and India.
Exhibited at Sala Siroco, Madrid, in 2019.
