45% of AI-generated code ships with security vulnerabilities (Veracode, 2025). Those are the flaws I catch. I am the React Native developer bring in to refactor AI-written and legacy React Native code, clean it up, and ship it safely to the App Store and Play Stor. 𝗧𝗼𝗽 𝗥𝗮𝘁𝗲𝗱 𝗣𝗹𝘂𝘀, 𝟳,𝟰𝟬𝟮 hours, 𝟯𝟯 five-star closes. My last Upwork clients came to me with an existing React Native codebase to refactor, not a blank repo. Recent React Native mobile work, every number verified on this profile: ⭐ $𝟭𝟮,𝟳𝟮𝟱 / 𝟱𝟬𝟵 hours - React Native audio app, a podcast and audiobook player with offline playback, shipped to the App Store 🏆 $𝟲,𝟭𝟴𝟲 / 𝟯𝟰𝟰 hours - long-running React Native frontend build and cleanup, delivered daily on aggressive timelines 🏆 $𝟮,𝟭𝟭𝟳 / 𝟭𝟰𝟬 hours - full stack React Native plus Node.js app, single developer owning the data flow end to end 🏆 $𝟭𝟬𝟬𝗞+ earned, 𝟵𝟲 percent Job Success across React Native mobile app development, refactoring and code cleanup. "Gopi went above and beyond the scope to help with fringe items to ensure customer satisfaction, all quickly and cheerfully. Responsive, reliable, and delivers clean work." - Upwork client, React Native developer engagement, 5-star close. Most inherited React Native apps were a web React developer's first mobile attempt, treated as a thin shell over a web app. That is why they arrive slow, crashing on Android, and stuck before the App Store. I take over that React Native code, refactor it against React Native CLI versus Expo trade-offs and real native module debugging, and get it production-ready. I take React Native mobile work only, never web React with mobile bolted on, and every React Native app I hand back is TypeScript throughout, tested on real iOS and Android hardware, and submission-ready. Named React Native mobile engagements: at Minutes AI I hardened a production React Native Expo app, refactoring for stability and performance across iOS and Android. For The Kitchen I took a cross-platform React Native mobile build on Expo and Supabase through App Store submission, then carried it into a second phase at the client's request. Earlier React Native developer roles at Gnan Infotech and Krishiv Infotech covered architecture through deployment on React Native CLI and Expo, so I refactor and ship React Native mobile app development at agency pace and solo. 𝗪𝗛𝗔𝗧 𝗜 𝗗𝗢 React Native codebase rescue and refactoring - taking over a legacy React Native mobile app from a previous React Native developer, clearing tech debt and dead code, and returning it to production. React Native code cleanup and AI-assisted refactoring - restructuring messy React Native code fast and safely, with Claude Code and Cursor speeding the refactor and test coverage. Performance optimization - React Native Reanimated animations, list virtualization, memory leak debugging, real-device tuning on lower-end Android. React Native mobile app development - production React Native CLI and Expo builds for iOS and Android, TypeScript throughout, App Store and Play Store ready. React Native plus Node.js full stack - a React Native frontend with a Node.js or Nest.js backend, REST and GraphQL APIs, one React Native developer owning it end to end. App Store and Play Store submission - code signing, provisioning profiles, review compliance, TestFlight and Internal Testing rollouts that pass on first submission. Native module integration - bridging native iOS and Android code where React Native alone cannot reach, in-app purchases and push notifications. 𝗪𝗛𝗢 𝗜 𝗪𝗢𝗥𝗞 𝗪𝗜𝗧𝗛 Teams inheriting a React Native mobile codebase a previous developer left half-finished, buggy, or unshippable. Founders and product teams launching a React Native mobile app in production, not a prototype. SaaS teams adding React Native mobile app development to an existing web product, where one React Native developer needs to own the whole mobile build. Agencies subcontracting React Native developer work where the delivery standard is App Store grade and the timelines are real. 𝗠𝗬 𝗣𝗥𝗢𝗖𝗘𝗦𝗦 Code review - a 24-hour turnaround reading your existing React Native code, flagging the tech debt and risk, and scoping the React Native developer work honestly. Refactor plan - what gets rewritten, what stays, the native module and API boundaries, and the App Store submission path, agreed before I touch the code. Build and clean - production React Native mobile code in TypeScript, real-device QA across iOS and Android. I use Claude Code and Cursor to move fast, then review every line so AI speed never becomes that 45% security risk. Ship and iterate - TestFlight and Internal Testing rollout, Sentry crash monitoring, App Store and Play Store release, then refinement on real user feedback. 🚀 Send me your existing React Native repo and I will send back a free 24-hour code review for the React Native developer work: no commitment required.
