Most Mobile App Development problems are not caused by code alone — they happen when React Native, backend APIs, payments, QA, and release are treated as separate pieces instead of one complete product. As a Senior Mobile App Developer and React Native Developer, I build, rescue, and scale production-ready iOS & Android apps with reliable backends, API integrations, payments, subscriptions, and AI-powered features. Whether you are starting from Figma, an MVP, or an existing codebase, I can take ownership from architecture and development through QA, App Store / Google Play release, and long-term production support. ★ 𝗠𝗬 𝗚𝗢𝗔𝗟 𝗜𝗦 𝗦𝗜𝗠𝗣𝗟𝗘 Build software you can keep growing — not software you have to rebuild six months later. Apps I’ve worked on have reached 200,000+ downloads, with experience across FinTech, SaaS, marketplaces, booking platforms, healthcare, wellness, subscriptions, payments, and AI-enabled products. ◆ 𝗖𝗢𝗥𝗘 𝗠𝗢𝗕𝗜𝗟𝗘 𝗘𝗫𝗣𝗘𝗥𝗧𝗜𝗦𝗘 Senior Mobile App Developer • Mobile App Developer • Senior React Native Developer • React Native Developer • Mobile App Development • React Native Development • iOS Developer • iOS Development • Android App Developer • Android App Development • AI Mobile App Developer • AI Mobile App Development • AI App Development • TypeScript • Expo • API Integration • Firebase • Supabase • Push Notifications • In-App Purchases • OpenAI API • Senior iOS Developer • Senior Android Developer • Cross-Platform Mobile App Developer • React Native App Developer • Mobile Application Developer • Cross-Platform App Developer 📱 𝗥𝗘𝗔𝗖𝗧 𝗡𝗔𝗧𝗜𝗩𝗘 | 𝗶𝗢𝗦 & 𝗔𝗡𝗗𝗥𝗢𝗜𝗗 As a Senior Mobile App Developer, I work across the complete Mobile App Development lifecycle: → React Native Mobile App Development → iOS & Android App Development → Cross-Platform Mobile App Development → Native iOS Development with Swift → Native Android Development with Kotlin → Expo / EAS builds and deployment → MVP development, app rescue, upgrades & migrations → Push notifications, real-time features, maps & location → In-App Purchases, subscriptions & Stripe payments → Performance optimization, bug fixing & crash resolution → App Store & Google Play submission If you need a React Native Developer for a new iOS & Android app or a Senior Mobile App Developer to take over an existing product, I can work across both product and technical delivery. 🤖 𝗔𝗜 𝗠𝗢𝗕𝗜𝗟𝗘 𝗔𝗣𝗣 𝗗𝗘𝗩𝗘𝗟𝗢𝗣𝗠𝗘𝗡𝗧 I integrate AI where it creates real product value: → AI Mobile App Development → AI-powered React Native apps → OpenAI API & LLM integrations → AI chatbots & intelligent assistants → Semantic search, embeddings & vector search → AI workflow automation → AI features for existing iOS & Android apps → AI-enabled SaaS products ⚙️ 𝗕𝗔𝗖𝗞𝗘𝗡𝗗 & 𝗙𝗨𝗟𝗟-𝗦𝗧𝗔𝗖𝗞 𝗦𝗨𝗣𝗣𝗢𝗥𝗧 A strong mobile app needs a reliable backend.
