Hire the Best Survey Freelancers in Surat, IN

I ship React Native apps fast using AI-assisted development (Cursor | Claude | Copilot | Codex): rapid features, upgrades, and store releases. React Native mobile specialist for mobile app development. 🔥 Top Rated Plus 🔥 70+ Android and iOS jobs 🔥 12+ years 🔥 Created Award Winning Android App "Apps of the Year Winner - TIME magazine and Womens Health" and "Happiest App in the World - Tristan Harris" 🔷 One of my success story: A restaurant group was two weeks from a pilot. Their RN app built locally but failed on CI. upgrades were half-done and releases kept slipping. I jumped in, used Cursor + Claude to accelerate refactors and write missing tests, finished the Expo→EAS migration, fixed iOS signing, stabilized Android native modules, and added offline order queuing with background sync. We shipped a TestFlight/Play build in under a month and used OTA (Expo Updates/CodePush) for same-day fixes during the first lunch rush. The app is now TabRabbit / TabRabbit POS, live across venues and processing thousands of orders daily. 🔷 What I do (React Native only) ✅ Upgrades & migrations: Expo/CLI, major RN jumps, Android/iOS build fixes, dependency conflicts ✅ Performance passes: cold start, bundle size, dropped frames, JSI/bridge profiling with Flipper ✅ Native integrations: Swift/Kotlin modules, Maps/Camera, background tasks, HealthKit/Google Fit ✅ Real-time & media: chat (Socket.io/WebSockets), WebRTC video/voice, offline sync ✅ Monetization & growth: RevenueCat/StoreKit/Play Billing, Stripe, deep links, GA4/Amplitude, A/B tests ✅ Release & reliability: EAS/Fastlane, signing/provisioning, privacy/Data Safety, staged rollouts, OTA (Expo Updates/CodePush), TypeScript, Jest/Detox, Crashlytics/Sentry, CI/CD 🔷 Skills i have: React Native • React Native Expo • Mobile App Development • iOS Development • Android App Development • TypeScript • Reanimated • React Navigation • EAS • CodePush • RevenueCat • Stripe • Firebase • WebRTC • Socket.io • HealthKit • Google Fit • GA4 • Amplitude • Crashlytics • Sentry • Flipper • CI/CD 🔷 FAQ: 1. Can you take over an existing RN codebase and stabilize it? => Yes. Typical rescue steps: dependency audit → RN/Expo SDK upgrade → build/signing fixes → crash/perf pass (Flipper, Crashlytics/Sentry) → CI/CD → OTA rollout. 2. How quickly can you ship a first release/MVP? => A focused RN MVP (auth, core screens, API, analytics, crash reporting) is often 2–4 weeks depending on scope and assets (designs, API readiness). 3. Do you handle App Store / Play Store submissions? => Yes. EAS/Fastlane, signing/provisioning, privacy labels & Data Safety, review fixes, and staged rollouts. I also set up OTA (Expo Updates/CodePush) for same-day hotfixes. 4. Do you sign NDA? => Yes. Please press the green "Contact" button if you want me to make an Android application for your business.
