I need a seasoned cross-platform developer who can take an idea from sketch to App Store and Google Play release using a single codebase. The end result should feel completely native on both iOS and Android—smooth animations, fast load times, and full compliance with each store’s guidelines. You’ll guide the technical stack choice (React Native, Flutter, or similar), set up the project, build out the UI, connect any required APIs, and implement analytics and crash reporting. Expect to manage the full cycle: coding, unit testing, device testing, store-ready builds, and post-launch bug fixes during the warranty period. Deliverables • Complete source code in a shared repo • Release-ready builds for iOS and Android • Basic setup documentation and store submission notes If you have apps live on both stores that showcase tight performance and modern UX, link them in your proposal so I can get a feel for your work.

Hi there, I understand you need a seasoned cross-platform developer to take your app from sketch to published releases on both App Store and Google Play using a single codebase, with native feel, smooth animations, store compliance, and a warranty period for fixes. Short plan (realistic, 3 steps): Tech & architecture: choose Flutter (recommended for pixel-perfect native feel and single codebase) or React Native if you prefer JS ecosystem; set up CI, analytics (Firebase/Amplitude) and crash reporting (Sentry). Build: implement UI, animations, API integration, unit and device testing, accessibility checks, and prepare store assets. Release & warranty: produce release-ready builds, submit to stores, resolve review feedback, and provide post-launch bug fixes during warranty. What I deliver: complete source in a shared repo, release-ready iOS & Android builds, store submission notes, unit tests, analytics/crash setup, and short deployment docs. I’ve shipped cross-platform apps with tight performance and smooth UX; I can share recent live app links and samples on request. I’m ready to start and will provide a milestone plan after a brief kickoff to lock scope. Best regards, Shuvadeep
