The Story
adidas Training was the biggest consumer app I'd worked on. The company ran on the Spotify model — tribes, squads, chapters — and I joined the Training squad as one of two iOS engineers who owned a slice of the product end to end.
It was also where I got to bet early on new Apple tech. SwiftUI had just shipped and most teams were waiting. I picked it up, built the first SwiftUI components in the app, and showed the rest of the chapter it was ready for real features.
Core Engineering Work
- 01Led the Workout Creator redesign from the first sketch through to release — it picked up an internal User Engagement & Content award in 2021.
- 02Built training-plan scheduling so people could commit to a routine instead of one-off sessions.
- 03Shipped the first SwiftUI views in a large, mostly-UIKit codebase and set the patterns others followed.
- 04Added an Apple Watch companion with WatchKit and wired up Siri shortcuts for starting workouts hands-free.
- 05Wrote and maintained a wide automated-test suite, and took on release-manager duties for the App Store cycle.
Analytics & Retention
Release management meant owning quality, not just code — coordinating the train, mentoring engineers, and keeping stakeholders honest about what was actually ready to ship.
