Kahf Kids is an Islamic education and entertainment app for children — curated YouTube videos, games, Quran, books, and courses behind a parent-controlled PIN — alongside a doctor-consultation surface (DocTime / Healthcare) that puts a VoIP call inside the app. I architected the original Flutter build, shipped it on Android, iOS, and Web, and ran it in production for about eighteen months while the user base grew.

Crewlix is an HR management mobile app for Android and iOS. It digitizes the daily HR operations of a modern workforce — attendance, leave, employee profiles, internal communication — behind a single login on a phone. I built it in Flutter, end to end, and shipped it to both stores.

A student app built once to last.

7+ years maintained, from Flutter 1.x through the latest stable
70+ feature modules in a single codebase
3 app stores — Google Play, App Store, and Amazon Appstore
Solo-owned for six years, then a team
Zero major production incidents across the whole window
One Clean Architecture refactor, made in year two — still in place

This is the project I point to when someone asks what “senior” means in mobile engineering. Not the flashiest build. The one that stays up.
