0 to 1 (Million Downloads): PUMA's Mobile Success Story
summary
PUMA’s React Native app hits 1,000,000 downloads in six months and ships fast: 39 releases in 51 weeks with gradual phased rollouts to limit blast radius. Errors land in Sentry with custom fingerprints and triage to find signal among ~1,000 issues. Localization uses placeholder-swap tooling and a PR check; accessibility improves via the published react native ammo library. Performance wins come from profiling in Flipper/react DevTools: caching Intl.NumberFormat halves initial product-list render time.
