Native mobile developer, Android first, iOS too. I build, fix and ship apps to Google Play and the App Store that still work six months after launch. ✅ 100% Job Success | Top Rated on Upwork ✅ Built the app that placed 1st nationally out of 120,000+ participants, live on Google Play ✅ Google Play Billing, Stripe and Paymob running in production ✅ Contributor to Appwrite's official Android SDK Most apps don't break at launch. They break three months in: the memory leak nobody profiled, the 80MB download, the crash that only fires on one OEM's build. That's the part I own. I work UK and EU hours, reply within four hours, and I'm still here when your app needs a fix a year after launch. 𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗 - Native Android in Kotlin and Jetpack Compose, Material 3, clean architecture - iOS in Swift and SwiftUI, extending and maintaining existing apps - Payments: Google Play Billing, Stripe, Paymob, Kashier, subscriptions, free trials, server-side receipt verification - Store release on both platforms: signing, data safety, testing tracks, target API level migration - Kotlin Multiplatform, sharing logic across Android and iOS from one codebase - Firebase and Appwrite backends, Cloud Functions, push, Crashlytics - App design in Figma, React admin dashboards, AI and LLM features - Rescuing inherited codebases, including Flutter, React Native and AI-generated builds 𝗪𝗛𝗔𝗧 𝗜'𝗩𝗘 𝗦𝗛𝗜𝗣𝗣𝗘𝗗 Arcadia, an AI-powered game tracker. Placed 1st nationally out of 120,000+ participants and shipped to Google Play. Mine end to end: concept, design, app, AI layer, store listing, growth. FlexPing, for a UK founder serving Amazon Flex drivers. Empty repo to a live, paying product on Google Play: three subscription tiers with a free trial, server-side receipt verification through Firebase Cloud Functions, a foreground service that survives Android's battery optimizer, and a cancellation flow that protects revenue instead of leaking it. Mine since the first commit and still maintained by me. PixelOne, a multi-tenant restaurant ordering and loyalty platform in Kotlin Multiplatform. One shared codebase across iOS and Android, a React admin dashboard, a Firebase backend in TypeScript, so a new restaurant onboards without a new build. A client put it better than I can: "exactly the kind of native Android engineer you want on a tricky bug." If that sounds like your project, click Message or Invite to Job at the top of this page and tell me what you're building. 𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞 I don't hand you generated code I can't explain. I use Claude Code and Cursor to move faster, but the architecture, the billing logic and the performance work are mine, and I'll walk you through any line of it on a call. I don't stop at the screen either. I own the design, the backend the app talks to, and the performance work most projects skip. When a subscription doesn't renew or a background job dies silently on a Samsung device, that's mine to fix, not a ticket I hand back. Most of my clients keep me on after launch, for feature work, target API migrations and the crashes that only show up at scale. 𝗪𝗛𝗘𝗥𝗘 𝗜'𝗠 𝗧𝗛𝗘 𝗪𝗥𝗢𝗡𝗚 𝗛𝗜𝗥𝗘 Single-screen jobs, cheapest-bidder work, and engagements about closing tickets rather than owning an outcome. And if you want cross-platform because it sounds cheaper rather than because it fits, I'll say so before you spend the money. 𝗪𝗛𝗘𝗥𝗘 𝗜'𝗠 𝗧𝗛𝗘 𝗥𝗜𝗚𝗛𝗧 𝗢𝗡𝗘 Your app takes payments, or needs to. You have real users and real revenue on the line, and you want someone still accountable for the code after launch. Tell me what's breaking. Click Message or Invite to Job and I'll give you an honest read on scope, stack and timeline before you commit.

Hi, I’m Mohammad — a full-stack developer with 14+ years of experience building web and mobile applications. I’ve spent the last few years working with startups and businesses to turn ideas into real, scalable products — not just prototypes. Some highlights: • Apps I worked on reached 1.5M+ downloads • Contributed to Fanzword, which raised $1.2M • Built platforms used by users across multiple countries What makes my work different: I focus on the product, not just the code. We don’t build traditional software… we build AI-powered systems tailored to each user. I use AI across development where it actually improves the experience, performance, or scalability - not just as a buzzword. I can help with: • Web & mobile app development • MVPs for startups • SaaS platforms • Custom E-commerce platforms • AI-powered features I prefer working on serious, long-term projects where I can contribute beyond just development. If you have an idea or an existing product you want to take to the next level, feel free to reach out.
