Flutter developer at JoodLab building offline-first Hajj and hotel apps for low-connectivity use.
TunisiaWhat I'm looking for
At JoodLab, I develop Flutter applications for hospitality and travel clients, including hotel operations and pilgrimage management. I apply Clean Architecture and BLoC, with offline-first features for users in low-connectivity environments.
I architected and shipped Jood Hajj, adding offline access, location tracking, ritual guides, and real-time support notifications. For QuickText, I led Flutter development and integrated Socket.io messaging, reducing average staff response time by 40%.
At Ostrix, I shipped Flutter applications for iOS and Android and improved app load time by 25% through API and caching optimizations. Earlier at Satoripop, I delivered mobile apps and led a feature rollout that boosted user retention by 20%.
