Expo on Mohammad Jashem — Senior Full-Stack Mobile Engineer

I’m Mohammad Jashem — a Senior Mobile Architect. This is the architecture deep dive for the React Native / Expo rebuild of Kahf Kids, the Islamic kids’ education app I migrated off Flutter after roughly eighteen months in production. The product is the same — curated video, Quran, books, games, courses, and a doctor-consultation feature (Healthcare / DocTime), all behind a parent-controlled PIN — and the device matrix is the same: low-end Android handsets with Mali and PowerVR GPUs that the Flutter platform-view hot path was ANR-ing on. The architecture underneath is new. This piece is the engineering write-up of that new shape: one React Native / Expo codebase and a shared monorepo package set targeting five platforms — Android, iOS, Web, Android TV, and web TV.

Flutter vs React Native vs Expo for MVPs

I’m Mohammad Jashem — a Senior Mobile Architect with 7+ years shipping Flutter, React Native, and Expo in production. I’ve kept one Flutter app alive for seven years across three stores, I’ve built an HR platform in Flutter because Flutter was the right call for that product, and I’ve also migrated a Flutter app off Flutter when the architecture stopped fitting. So when founders ask me “Flutter or React Native or Expo for the MVP,” my answer is never “it depends.” It depends on what — and I can tell you the what in about ten minutes if you describe the product.

I’m Mohammad Jashem — a Senior Mobile Architect. This is the story of moving Kahf Kids off Flutter after roughly eighteen months in production: why the call was forced, what I rebuilt, and how it shipped in three months with an AI-assisted workflow. Not the marketing version — the engineering one.
