Building for the next Billions
summary
Targets "TikTok generation" users who expect fast, simple, low-friction experiences; recommends using Flutter for cross‑platform responsiveness and Firebase for offline syncing. Prioritizes problem solving over features, enforces small assets (avoid 5 MB images, aim for ~11 KB), trims APK bloat (example: a 150 MB build caused crashes), designs for variable connectivity and localization, measures battery and memory use, keeps clean architecture, and runs closed betas and unit tests before wide release.
