React Native Developer | Delivered 25+ React Native Apps with 10,000+ Users Across Multiple Apps on iOS & Android |
I design and build high-performance mobile applications using React Native for businesses that care about speed, stability, and long-term scalability.
With 7+ years of experience in mobile app development, I’ve worked on apps ranging from early-stage MVPs to large-scale production applications used by thousands of users across iOS and Android. My focus is always on clean architecture, smooth UX, and maintainable code — not just “getting the app working.”
Most of my clients come to me when they need:
• A React Native app built the right way from day one
• An existing app fixed, optimized, or refactored
• A smooth cross-platform solution without compromising performance
• Reliable communication and long-term technical ownership
I work comfortably with:
• Custom UI/UX implementations
• REST & GraphQL API integrations
• Real-time features and third-party SDKs
• App performance optimization
• App store deployment & compliance
I don’t disappear after delivery. I think in terms of product stability, updates, and future growth.
I also represent a small but efficient team of mobile developers and backend engineers. We help startups and SaaS businesses build end-to-end solutions — from MVP to production-ready systems. I work with early-stage founders, product managers, and agencies that need reliable and long-term technical partners.
Industries I've worked in:
☑️ Health & fitness
☑️ E-learning
☑️ Ride-sharing

☑️ Expo / Bare Workflow
☑️ Redux, Context API, Zustand
☑️ Push Notifications (FCM/APNs)
☑️ Google Maps, Stripe, Twilio, Razorpay, OneSignal, WebRTC

React Native Developer focused on Mobile App Development for iOS and Android using React Native, Expo, TypeScript, Firebase, and Supabase. I help startups and businesses build new apps, rescue unstable codebases, improve performance, and ship reliable releases to the App Store and Google Play.
Most clients reach out when they need more than someone who can complete tickets. They need a developer who understands the product, identifies risks early, and takes ownership from architecture to production.
📱 𝗥𝗘𝗔𝗖𝗧 𝗡𝗔𝗧𝗜𝗩𝗘 & 𝗠𝗢𝗕𝗜𝗟𝗘 𝗔𝗣𝗣 𝗗𝗘𝗩𝗘𝗟𝗢𝗣𝗠𝗘𝗡𝗧
React Native mobile app development is my core specialization. I work on new products and existing iOS and Android apps that need upgrades, fixes, scaling, or long-term support.
◈ React Native apps from scratch
◈ Expo and React Native CLI applications
◈ Expo SDK upgrades, EAS Build, and migrations
◈ TypeScript and JavaScript development
◈ iOS and Android native integrations
◈ API integration, authentication, and user management
◈ Firebase and Supabase integration
◈ Push notifications, deep linking, and background tasks
◈ Maps, GPS, geolocation, and real-time tracking
◈ Camera, media, documents, and file uploads
◈ Real-time chat and WebSockets
◈ Stripe, subscriptions, and in-app purchases
◈ Performance optimization, crash fixing, and app rescue
◈ App Store and Google Play deployment
I do not treat React Native as “one codebase and the job is done.” Production apps still require careful handling of native SDKs, permissions, background behavior, platform differences, performance, store requirements, and release stability.
⚡ 𝗘𝗫𝗣𝗢 • 𝗶𝗢𝗦 • 𝗔𝗡𝗗𝗥𝗢𝗜𝗗
I use Expo for fast, maintainable cross-platform development and reliable release workflows. I work with Expo Router, EAS Build, EAS Update, notifications, deep links, and native configuration.
When deeper native functionality is required, I can work with Swift/SwiftUI on iOS and Kotlin/Java on Android for native modules, SDK integrations, permissions, background services, and platform-specific fixes.
The goal is simple: the app should feel stable and polished on real iOS and Android devices—not only in development.
🚀 𝗦𝗘𝗟𝗘𝗖𝗧𝗘𝗗 𝗣𝗥𝗢𝗗𝗨𝗖𝗧 𝗘𝗫𝗣𝗘𝗥𝗜𝗘𝗡𝗖𝗘
◆ VehicleTransportHub — transportation marketplace with provider matching, instant quotes, booking, tracking, ratings, dashboards, and mobile workflows.
◆ MobileWash Pro — field-service product with customers, technicians, jobs, estimates, invoices, payments, refunds, and operations.
◆ PLEIS — multi-role platform covering organizations, venues, events, reservations, dashboards, filters, and loyalty workflows.
◆ Tempy — healthcare staffing workflows involving jobs, bids, shifts, time tracking, messaging, reviews, and notifications.
I have also worked on marketplace, booking, logistics, healthcare, field-service, subscription, social, and real-time communication products.
🔗 𝗕𝗔𝗖𝗞𝗘𝗡𝗗 & 𝗔𝗣𝗜 𝗦𝗨𝗣𝗣𝗢𝗥𝗧
My primary focus is Mobile App Development, but I can also own the backend systems the app depends on.
▸ Node.js, Express.js, and NestJS
▸ REST APIs and WebSockets
▸ PostgreSQL and MongoDB
▸ Firebase and Supabase
▸ Authentication and role-based access
▸ Stripe and payment workflows
▸ Cloud integrations and deployment
This helps when a mobile issue is actually caused by an API, database, authentication, payment, or real-time layer. I can trace the complete flow instead of treating each layer separately.
🤖 𝗣𝗥𝗔𝗖𝗧𝗜𝗖𝗔𝗟 𝗔𝗜 𝗜𝗡𝗧𝗘𝗚𝗥𝗔𝗧𝗜𝗢𝗡
Where useful, I integrate OpenAI APIs, AI assistants, intelligent search, recommendations, document processing, summarization, voice workflows, and automation—without making AI the main identity of the product.
🧭 𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞
For existing apps:
→ Reproduce the issue
→ Find the root cause
→ Check related workflows
→ Fix and test
→ Verify related areas
For new apps:
→ Understand the product and business rules
→ Identify architecture and integration risks
→ Define practical milestones
→ Build for maintainability
→ Test on real devices
→ Prepare for production release
I work well from written requirements and async communication, while raising questions early when a decision can affect cost, timeline, security, or architecture.
