I'm Hashim, a Flutter developer specializing in mobile app development for founders and startups. I turn your idea into a production-ready iOS & Android app that real users actually download, not a prototype that sits in TestFlight. I'm Hashim, a full-stack Flutter developer with 3 years of hands-on experience shipping iOS & Android apps end-to-end from architecture to App Store and Play Store release. 𝐌𝐘 𝐀𝐏𝐏𝐑𝐎𝐀𝐂𝐇 𝐓𝐎 𝐁𝐔𝐈𝐋𝐃𝐈𝐍𝐆 𝐌𝐕𝐏𝐒: For most products, I build fast and lean with Flutter + Firebase or Supabase you get a real, scalable app in front of users quickly without overspending. When a product needs full custom logic, I build a dedicated Node.js backend with REST APIs that scales as you grow. 𝐀 𝐟𝐞𝐰 𝐫𝐞𝐬𝐮𝐥𝐭𝐬 𝐈'𝐯𝐞 𝐝𝐞𝐥𝐢𝐯𝐞𝐫𝐞𝐝: ✅ Built and launched a flagship social app 1,000 active users in the first 20 days, scaling to 3,000+ users within 3 months. ✅ Built a football training platform for a UK client with HLS video streaming (AWS S3 + CloudFront) now serving 1,900+ active users. ✅ Shipped 70+ pixel-perfect screens in 25 days from Figma for a marketplace MVP, delivered fully functional within 2 months. ✅ Diagnosed and fixed critical security, payment, and notification bugs on a live B2B payment app restored a broken product back to the stores. 𝐖𝐡𝐚𝐭 𝐈 𝐜𝐚𝐧 𝐛𝐮𝐢𝐥𝐝 𝐟𝐨𝐫 𝐲𝐨𝐮: ✅ Cross-platform mobile apps (Flutter — single codebase, iOS + Android) ✅ MVP development with a clear path from idea to launch ✅ Firebase / Supabase backends — Auth, database, storage, real-time ✅ Custom Node.js backends — REST APIs, scalable architecture ✅ Real-time features — chat, live tracking, notifications (WebSockets, SignalR) ✅ Payments & subscriptions — Stripe, In-App Purchases ✅ AI-powered app features — OpenAI / Claude integration ✅ Admin panels & dashboards (Flutter Web) ✅ CI/CD pipelines (GitHub Actions) for automated builds & releases 𝐇𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤: I build with Clean Architecture and SOLID principles, so your codebase stays maintainable as it grows. You get clear communication, regular updates, and code you own from day one. I also use AI-assisted development (Cursor, Claude) to ship faster without cutting corners on quality. If you're looking for a developer who owns outcomes not just tasks and can take your app from zero to launch, send me a message and let's talk through your idea.
