01Constraint
A live app shipping about every six months. On iOS it ran under 10 fps; on Android it was not playable, at 3 to 5 fps on a mid-range phone (Fig. 02.1) and not running at all on low-end devices.
02Intervention
I led the team through it. Together we set up CI/CD and build automation, moved to disciplined biweekly sprints, ran targeted performance passes to port the app to low and mid-range Android, and used analytics dashboards to see what users actually did.
03Measured
Frame rate on fixed test devices, release cadence and escaped defects.
04Result
The app ported to low and mid-range Android, 50+ biweekly deliveries between December 2023 and January 2026, from under 10 fps to a stable 60 on mid-range Android, and 80%+ fewer escaped defects.
05What it proves
I fix the delivery system before chasing features.
