10k+ downloads, 5k+ MAU, 99.7% crash-free — Bangladesh's top OTA travel app.
The problem
Bangladeshi travellers relied on fragmented booking channels — phone calls, in-person agencies, and slow web portals — with no mobile-first experience for comparing flights and completing payment in one flow.
The approach
- Built flight search and booking flows on Bloc state management with GraphQL for real-time flight data feeds.
- Integrated Firebase Auth, Analytics, and Crashlytics — raising crash-free sessions to 99.7%.
- Owned the Android release pipeline: signing configs, R8 shrinking, Play Console staged rollouts, and multi-environment dev/staging/prod builds.
- Rebuilt core booking screens to reduce UI-state bugs and standardise async data handling.
The results
- 10,000+ downloads and 5,000+ monthly active users.
- 99.7% crash-free session rate.
- Live on both App Store and Google Play in Bangladesh.
