The challenge
Parcel volumes do not grow smoothly — they detonate around holidays, sales and Mondays. The app had to stay instant while lockers filled, couriers rerouted and millions of users checked tracking at the same time. Anything slower than a glance becomes a one-star review.
What we built
- Native iOS and Android apps with offline-first tracking and pickup flows.
- Backends and integrations scaled for peak-season traffic multiples.
- Locker, courier and returns journeys tuned release after release.
- Release train with staged rollouts, monitoring and fast rollback.
How we worked
One senior team across product, design and engineering — weekly increments, CI/CD everywhere, QA sign-off before anything reached users. Small blast radius first: every risky change shipped behind flags to a slice of traffic before going wide.
The result
An app Poland opens every day: 10M+ downloads with a 5.0 App Store rating — proof that scale and craft can ship together when one accountable team owns the whole journey.
