Right now, most SaaS founders and businesses are losing users and revenue because their apps are not optimized for mobile, their App Store submissions get rejected, their Stripe or Supabase setup breaks on mobile, or their AI-powered systems are not working as expected. That’s where I come in. I help you convert, build, fix, and scale high-performance mobile apps and AI SaaS systems using Claude Code, React Native Expo, OpenClaw, and modern vibe coding tools without trial and error. ⚠️ If You’re Experiencing Any of These: ❌ Your web app needs to be converted to iOS & Android ❌ Apple keeps rejecting your app or it behaves like a webview ❌ Stripe payments or Supabase auth not working on mobile ❌ Your Lovable, Replit, or Base44 app is broken or incomplete ❌ Your AI SaaS or automation system is not performing ❌ Push notifications, offline mode, or native features missing 👉 You’re losing users, retention, and revenue every single day. ✅ 𝐖𝐡𝐚𝐭 𝐈 𝐃𝐨 (𝐀𝐧𝐝 𝐃𝐨 𝐁𝐞𝐭𝐭𝐞𝐫 𝐓𝐡𝐚𝐧 𝐌𝐨𝐬𝐭): 🔥 Web App to Mobile App Conversion Done Right No weak webviews. I convert your web app into a real mobile app using React Native, Capacitor, or Expo with native performance and smooth UX. 🔥 AI SaaS & MVP Development That Actually Works I build scalable AI SaaS apps and MVP platforms using Claude Code, OpenClaw, Gemini, and modern stacks designed for real-world usage and growth. 🔥 Vibe Coding & AI App Development From Lovable, Replit, and Base44 apps to full AI-powered systems, I fix, rebuild, and optimize apps using advanced AI assisted development tools. 🔥 Mobile App Deployment & Store Approval I handle App Store and Google Play submission, fixing rejection issues, optimizing performance, and ensuring your app gets approved and live. 🔥 OpenClaw Automation & Backend Systems I build smart automation workflows, API integrations, and backend systems that reduce manual work to your business operations. 💰 𝐖𝐡𝐚𝐭 𝐘𝐨𝐮 𝐆𝐞𝐭: ✔️ High-performance mobile apps (iOS & Android) ✔️ Faster App Store approval & successful deployment ✔️ Working Stripe, Supabase, and backend integrations ✔️ AI-powered SaaS systems that scale with your business ✔️ Clean UI/UX with smooth performance and real native experience ✔️ Less manual work, more automation, more revenue 🧠 𝐖𝐡𝐲 𝐇𝐢𝐫𝐞 𝐌𝐞? Most developers: ❌ Build slow webview apps ❌ Break features during conversion ❌ Don’t understand deployment or AI systems I don’t. I understand both: ✔️ Mobile app architecture (what gets approved & performs well) ✔️ AI SaaS systems & automation (what actually works in production) That combination is why my clients don’t come back saying 👉 “It’s not working.” ⚡ Let’s Be Direct: If your app is not optimized for mobile, not deployed properly, or your AI system is not working… You are already losing users, growth, and revenue every single day. 📩 Next Step: Send me a message or invite me to your job.

React Native + Expo developer who takes apps from an empty repo to live on the App Store and Google Play. Five years in, usually the only mobile engineer, shipping AI, health, and marketplace apps and rescuing the ones that crash, lag, or get rejected Some of what I've shipped: Fitra360: an AI wellness platform that analyzes DNA, bloodwork, symptoms, and lifestyle data to generate personalized health and routine plans. FIXA: a car services and AI diagnostics app with camera-based tire scanning and Elasticsearch-powered search, in production. Gayar: Kuwait's first car parts marketplace. Three years in production with full ad-platform integration (TikTok, Snap, Meta, Google) and deep-linked campaigns. Other production work spans health insurance telemedicine, Saudi enterprise ERP (POS, inventory, geofenced HR attendance), university apps with campus security systems, and AI-assisted real estate platforms. The work tends to land in two buckets. New builds: production React Native + Expo apps from MVP through enterprise scale. AI features like health analysis, in-app assistants, image recognition, and smart recommendations. Healthcare and telemedicine platforms with video consultations, secure data, and prescriptions. Marketplaces and e-commerce apps with deep linking and full event tracking. Enterprise ERP, POS, inventory, and HR systems. Supabase, Firebase, and GraphQL backends (auth, RLS, realtime, edge functions, storage). Pixel-perfect UI from Figma, REST and GraphQL APIs, push notifications, in-app purchases, geolocation, maps, geofencing, deep linking. App Store and Google Play submissions end-to-end, including rejection appeals. Rescues: crashes, white screens, broken navigation. Performance issues like slow lists, laggy animations, high memory, slow cold start. Auth and session problems (Supabase, Firebase, OAuth, expo-auth-session). App Store and Play Store rejections. TestFlight build and distribution issues. Send a quick description, a Loom, or an error log. I'll come back with a clear plan, a realistic timeline, and what it'll actually take.

I don't just write React Native code. I ship apps people actually use. 1M+ downloads. 30+ countries. 200+ projects. 100% Job Success. Most clients come to me when their React Native app is stuck, broken, or half-built and nobody else could finish it. Or when they need a mobile app developer who handles everything from first screen to App Store and Google Play launch. Some come with an MVP idea and need a react native developer who moves fast without cutting corners. Others come because their react native mobile app has performance issues or complex integrations nobody else could solve. I've been doing this for 8+ years, delivered 200+ projects, and the apps I've built as a mobile app developer now serve 590K+ users across 30+ countries.

Firebase, Supabase, and Node.js on the backend — one team, one codebase, one point of contact. INDUSTRIES I've shipped products as a mobile app developer and mobile application developer across multiple verticals.

Clients who need an app developer ios android with full backend ownership also work with me on ios android developer projects. I collaborate with flutter developer and android developer teams when needed, and I structure codebases that a python developer or backend node.js team can extend later.
