I already have a complete project hosted on Railway with the code in a public GitHub repo. What I need now is a seasoned mobile developer who can take that existing backend and transform it into fully-functioning native apps for both Android and iOS. You should feel comfortable cloning the repo, setting up your local environment, and wiring the current endpoints into a clean, stable mobile codebase. Experience submitting apps to the App Store and Google Play is important, because once we are feature-complete I’d like you to guide the entire release process. To give you a sense of scope, here is what I consider a successful hand-off: • Android and iOS builds that compile without errors and mirror current web functionality • All source committed back into my GitHub repo with clear, concise commit messages • TestFlight / internal testing builds delivered for review • Final store submissions accepted by Apple and Google If you’ve worked with Railway deployments before, all the better—you’ll understand the environment the APIs are coming from. Send over links to any live apps or GitHub projects that demonstrate similar work, and let me know roughly how long the full cycle—from setup to store approval—has taken you in the past. I’m ready to start as soon as we find the right fit.

Interesting project, I will clone your Railway-hosted repo, wire every existing endpoint into native Android and iOS apps, deliver TestFlight and internal testing builds, and handle the full App Store and Google Play submission process. One approach worth considering — building with React Native or Flutter so both platforms share a single codebase while still producing native binaries. This cuts development time significantly and means future updates only need one code change instead of two. I will structure the project so all source commits back to your repo with clear, descriptive messages at each milestone. Questions: 1) Is the backend a REST API or GraphQL — and does it require authentication tokens or OAuth? Send me a message and we can go over the details. Best regards, Kamran

Hi - the key here is not just wrapping your Railway backend into mobile apps, it is making sure the mobile experience handles real-world states like slow networks, expired sessions, and partial API responses without breaking. User opens app - logs in - app calls Railway APIs - data loads into mobile UI - user performs actions - backend updates - UI reflects changes instantly - builds are tested via TestFlight/Play Console. Looks correct, but fails when mobile state gets out of sync with backend responses. API timing or auth issues can cause broken flows in real use, so I handle it with structured API layers, retry handling, and session management. Input - existing API endpoints. Processing - mobile app logic. Output - stable iOS/Android apps. The part to get right early is API integration and state handling.

Hi there, I have read your project requirement. You need native Android and iOS apps built on top of your existing Railway-hosted backend, with full API integration, clean mobile architecture, and complete support through testing and App Store/Play Store submission. We can take your current GitHub repo, set up the environment, and build stable mobile apps using either native (Kotlin + Swift) or a cross-platform approach (Flutter/React Native) depending on your preference. The apps will mirror your web functionality, integrate seamlessly with your APIs, and follow best practices for performance, security, and maintainability. We will also manage TestFlight/Internal Testing and guide you through final store approvals. A few quick questions to proceed: =========================== Do you prefer native apps or a single cross-platform codebase? Is your API fully documented and production-ready? Are UI/UX designs already available or should we adapt from the web app? Do you have Apple Developer and Google Play accounts set up? Best Regards, Srashtasoft Team

Hi there, I’ve reviewed your Railway-based backend and the goal to turn it into polished native apps for Android and iOS. I will clone your repo, set up a clean local environment, and wire the existing endpoints into a stable mobile codebase that mirrors the web functionality. My plan includes building robust native apps, implementing clean architecture, and ensuring the backend calls are reliable, with thorough QA. You’ll get clear, concise commit messages pushed back to your GitHub repo, and I’ll guide the TestFlight and Google Play release steps from internal testing to store approval. I’ve worked with Railway deployments before, so I’ll hit the ground running and align closely with your API environment while keeping the apps responsive and well-tested. What is your target release timeline and are there any must-have integrations or parity requirements beyond the current web app? Best regards,

It can be overwhelming to have your Railway project ready but not see it live as native apps, especially when you want the Android and iOS versions to mirror your web experience perfectly. Handling everything from cloning the repo to getting clean builds and then navigating the App Store and Google Play submission hurdles can be a real drain on your timeline. You can expect smooth, error-free native apps for both platforms that reflect your current backend, all fully prepped for internal review and final store acceptance. First, I will clone your public GitHub repo and get the local environment set up to connect with your existing APIs. Next, I will build out the Android and iOS apps to match your web features and commit all progress with clear notes. Finally, I will prepare test builds for review and guide the apps through to successful store submissions. What part of the current web functionality do you want to see prioritized first in the mobile apps?

I can clone your Railway-hosted backend repo and build clean native apps for both Android and iOS that replicate the current web features. I’ve done similar work turning web APIs into mobile apps for clients, and quickly setting up the environment and wiring endpoints is straightforward based on past projects. Once the apps build without errors, I’ll commit all code with clear messages back to your GitHub repo. For testing, I’ll deliver TestFlight builds and Android internal testing versions so you can review functionality as we go. A couple of questions to align expectations: Are there specific UI components or navigation flows from the web version you want replicated exactly, or is redesign flexibility okay? Also, are there push notifications or offline capabilities planned? From setup to store approval, similar end-to-end projects I’ve done took around 3-4 weeks, including app store reviews. I’m ready to get started as soon as you share the repo and details so we can hit the ground running.
