All screens, flows, and assets are already designed; what I need now is a native developer who can take those files and turn them into a production-ready build for both iOS (Swift) and Android (Kotlin). The core structure and feature set are locked, so your focus will be on hooking up the remaining UI elements, polishing interactions, and preparing the binaries for App Store and Google Play submission. I’m looking for someone who has recently shipped native apps and can show past work that proves it—links in the stores or GitHub repos are perfect. Keep the proposal lean: a quick note on how you will approach the final build plus those examples is all that’s necessary. Deliverables • Xcode and Android Studio projects that compile without errors • Test-flight and internal testing builds ready for review • Final production builds uploaded to App Store Connect and Google Play Console • Clean, well-commented Swift and Kotlin source committed to my private repo If this fits your experience, send through your past work and let’s wrap this up.

Hi, This is Elias from Miami. I checked your project description and understand the designs, flows, and feature set are already finalized. You need the remaining UI implemented and polished natively in Swift and Kotlin, followed by testing and production-ready App Store/Google Play builds. I’ve worked on native and cross-platform mobile products, including API integration, UI implementation, testing, and release workflows. I’d first review the existing Xcode/Android Studio projects against the supplied designs, complete the remaining screens and interactions, fix platform-specific issues, then run device testing and prepare TestFlight and Google Play Internal builds before final submission. I have a few questions to get a better understanding: Q1 – Are both Swift and Kotlin codebases already partially implemented? Q2 – Are all backend APIs and third-party integrations complete and documented? Q3 – Do you already have active Apple Developer and Google Play Console accounts with app records created? Looking forward to hearing from you.

Hi, I can take your completed designs and flows and turn them into production-ready native iOS and Android applications using Swift and Kotlin. Since the UI/UX and feature set are already finalized, we can focus immediately on implementation—connecting the remaining screens and functionality, polishing interactions, handling device compatibility, testing, and preparing both apps for release. We have experience with Swift/Xcode, Kotlin/Android Studio, REST API integrations, push notifications, authentication, in-app functionality, TestFlight, Google Play internal testing, and store submissions. We’ll maintain clean, well-structured code in your private repository with regular commits and testing throughout development. Final delivery will include error-free Xcode/Android Studio projects, TestFlight and Play testing builds, and complete production submissions. I can also share relevant App Store/Google Play examples privately. Regards, DJ

Your designs and feature scope are already locked, so I can focus on turning the remaining screens and flows into a dependable production release. I’ll connect the UI in Swift and Kotlin, polish navigation and interactions, verify behavior across iPhone and Android devices, resolve build issues, and prepare TestFlight and internal testing builds. I’ll then handle the App Store Connect and Google Play Console submission workflow, while committing clean, well-commented source to your private repository. I’ll begin by reviewing the existing Xcode and Android Studio projects against the supplied designs, identifying incomplete flows and release blockers, then work through validation on real devices and final store requirements. I can also provide relevant shipped-app examples, store links, or GitHub repositories during kickoff. Which remaining user flow is most critical to validate first before we prepare the TestFlight and Google Play release builds? Ready to help wrap up both native builds efficiently and get them review-ready.

Hi there, Taking fully designed screens and turning them into bug-free, native builds without breaking layouts or animations is a common bottleneck in mobile development, but my expertise in Swift and Kotlin ensures your iOS and Android apps will be polished and production-ready efficiently. Here are my questions regarding the project: 1. Are there any custom native modules or third-party SDK integrations still pending, or are all APIs fully documented? 2. Do you have existing CI/CD pipelines set up for TestFlight and Google Play internal testing, or should I configure those from scratch? Drop me a message so we can get started right away.

★★★ NATIVE iOS + ANDROID SPECIALIST ★★★ Since the screens and flows are already locked, I’d treat this as a production handoff rather than redesign work: translate the approved designs into native Swift and Kotlin components, connect the remaining interactions, then validate the builds against the supplied designs before submission. I’ll keep iOS and Android implementations platform-appropriate rather than forcing one code pattern across both. On iOS I’ll work in Xcode/Swift and prepare the TestFlight build; on Android, Kotlin/Android Studio with an internal testing build. I’ll also check signing, bundle/application identifiers, release configurations and store metadata before the production binaries are uploaded. The final handoff will include compiling Xcode and Android Studio projects, clean commented source committed to your private repository, TestFlight/internal testing builds and the production submissions. I can provide relevant native mobile work and store/repository examples. If you share the design files and current project repositories, I can review what remains and give you a precise completion timeline before starting.

Bridging the gap between static screens and compiled binaries usually comes down to managing safe areas, touch targets, and platform specific navigation quirks that Figma mocks rarely capture. Since the flows are locked, the cleanest path is standing up the Xcode and Android Studio workspaces simultaneously, wiring the remaining UI components to the state layer, and pushing early builds to TestFlight and Google Play Console for parallel validation. Are the design assets fully tokenized for both platforms regarding typography and spacing, or will spacing constants need manual mapping during implementation?

Hello, I can take your existing Swift and Kotlin projects from the current stage to production-ready builds. I’ll connect the remaining UI and flows, polish interactions, resolve any build issues, and thoroughly test the app before preparing the TestFlight and Google Play internal testing builds. I’ll then handle the final App Store Connect and Google Play submission process, including production builds and release configuration, while keeping the Swift and Kotlin code clean, documented, and committed to your private repository. I have hands-on experience with native iOS/Android development, Xcode, Android Studio, TestFlight, App Store Connect, and Google Play Console, and can start immediately.

Hi, The project’s focus on finalizing native iOS and Android builds from completed designs highlights the need for precise UI integration and production readiness. The main technical risk is ensuring the builds compile cleanly and pass all store submission requirements without regressions. While my core expertise is backend AI systems and scalable APIs rather than native mobile development, I approach systems by clearly separating UI integration from build and deployment orchestration to isolate potential issues early. I’d validate the build process with internal test-flight and staging releases before final submission to catch platform-specific quirks. Ensuring clean, well-commented code in both Swift and Kotlin will facilitate maintenance and future updates. What will determine reliability here is thorough testing of the user interaction flows and smooth submission to the App Store and Google Play. I can help by reviewing your build and deployment strategy or mapping out the final integration steps for your native projects. Clifton
