Kahf Kids Flutter Clean Architecture: Riverpod, Auto Route

mjashem@hotmail.com (Mohammad Jashem) — Sat, 18 Jul 2026 00:00:00 +0600

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.

Kahf Kids React Native / Expo Architecture: Mobile, Web, TV

mjashem@hotmail.com (Mohammad Jashem) — Sat, 18 Jul 2026 00:00:00 +0600

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.

Kahf Kids SEO Architecture: Meta Injection + Sitemaps

mjashem@hotmail.com (Mohammad Jashem) — Sat, 18 Jul 2026 00:00:00 +0600

I’m Mohammad Jashem — a Senior Mobile Architect. This is the SEO spoke for Kahf Kids, the Islamic kids’ education app I migrated from Flutter to React Native / Expo after about eighteen months in production. The product runs curated video, Quran, books, games, and courses behind a parent-controlled PIN, and the web build ships out of the same React Native / Expo codebase as the mobile apps — documented across the cluster. This piece is narrow on purpose: the engineering decision that got a client-rendered kids’ video app actually indexed by Google — meta-injection into the SPA shell, not full server-side rendering.

Crewlix Flutter Clean Architecture: HR App Deep Dive

mjashem@hotmail.com (Mohammad Jashem) — Fri, 17 Jul 2026 00:00:00 +0600

I’m Mohammad Jashem — a Senior Mobile Architect. Crewlix is an HR management app I built in Flutter and shipped to Google Play and the App Store: attendance, leave, employee profiles, and a social feed. This is the architecture write-up — not the marketing version, the engineering one.

AI Code Review in CI/CD: From Slow Reviews to Instant

mjashem@hotmail.com (Mohammad Jashem) — Wed, 08 Jul 2026 00:00:00 +0600

Review latency is the quietest killer of release cadence on a long-running app. The build ships in minutes, the pipeline promotes in minutes, and then a PR sits for a day and a half waiting for a human to look at it. I’m a senior mobile architect — I’ve maintained the NCC App for seven-plus years across three stores — and for a long stretch the bottleneck on my own pipeline was me. Adding AI code review to CI/CD is the single change that collapsed that latency. This is the write-up on how it’s wired, what it catches, what it misses, and why a human still signs off on every merge.

Flutter Platform-View ANRs on Mali/PowerVR GPUs

mjashem@hotmail.com (Mohammad Jashem) — Wed, 08 Jul 2026 00:00:00 +0600

This is the investigation I wish someone had handed me before I spent six weeks patching a Flutter platform-view ANR I couldn’t fix in app code. It’s the engineering detail behind our full comparison of Flutter vs React Native vs Expo and the failure mode that ended in migrating Kahf Kids off Flutter. Dev forums are full of “Flutter WebView ANR on Redmi Note” threads with no real answers — most blame the WebView, tell you to enable hybrid composition, or say clear the cache. None of that fixes this.

Maintaining a Flutter App for 7 Years

mjashem@hotmail.com (Mohammad Jashem) — Wed, 08 Jul 2026 00:00:00 +0600

I’m Mohammad Jashem — a Senior Mobile Architect, and for the last 7+ years I’ve been the maintainer of the NCC App, the student-assistance app for Northwest Career College. It started on Flutter 1.x in 2019. The current build runs on Flutter 3.41.x stable, with Dart 3, Impeller, and Material 3. Same codebase. Same store listings — Google Play, App Store, Amazon Appstore. Zero major production incidents across the entire window.

Why I Migrated Kahf Kids from Flutter to React Native/Expo

mjashem@hotmail.com (Mohammad Jashem) — Wed, 08 Jul 2026 00:00:00 +0600

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.
