I’m Mohammad Jashem — a Senior Mobile Architect. Kahf Kids is an Islamic kids’ education app I built in Flutter and ran in production for about eighteen months across Android, iOS, and Web: curated YouTube videos, Quran, books, games, courses — all behind a parent-controlled PIN. This is the architecture write-up. Not the marketing page — the engineering one.

At a glance
#

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.
