I am building a retro gaming app. I already have the backend, an existing frontend foundation, and Figma designs. I need a front-end developer to connect the UI to the backend, polish the app flow, and create a working Android APK for testing. This is not a static Figma-to-HTML job. The app needs to connect to real backend APIs and work as an installable mobile app. The first goal is an Android APK, but I also want the technical path to support an iOS/App Store release later, so please do not choose an approach that only works for Android. -- Important Note About Figma Screens -- The Figma file has many frames, but many are only button states, modals, menu states, tab changes, loading states, or page updates. Figma access will only be provided to the selected candidate or finalist after an initial conversation, NDA/contract agreement, and confirmation that the developer understands the scope. The first milestone should include a simple screen inventory that separates: - real screens/pages - reusable components - modals - button/menu states - loading/empty/error states -- What I Need Built -- The app should allow a user to: - open the app - browse game systems - view game lists - open a game detail page - launch a game - use mobile controls - log in or use the approved account flow - save/load progress where supported - view account/profile screens - see clean loading, empty, and error states -- Technical Skills Needed Please apply only if you have experience with: - React / [login to view URL] - mobile responsive UI - REST API integration - Android APK builds - Capacitor, Android WebView, or similar mobile app packaging - ideally iOS build planning as well - debugging mobile browser/WebView behavior Experience with browser-based game players, EmulatorJS, retro gaming apps, or media-heavy apps is a plus. -- Deliverables -- I need: 1. Connected frontend screens 2. API integration 3. Working Android APK 4. Build instructions 5. Notes on any backend issues or missing API fields 6. Basic QA checklist 7. Recommended path for future iOS/App Store release I am looking for someone practical and honest who can get this working without overcomplicating the project. I have a two additional app projects lined up right after this one, so I am looking for someone reliable who can potentially continue working with me if this first project goes well. The designer that worked on this project is already working on the next two projects now.

Hi - Retro gaming app work doesn’t drift because screens are hard to connect, it drifts when Figma states, API responses, WebView behavior, game launch, controls, and save data are not treated as one playable flow. The real flow should be: user opens the APK - logs in or continues through the approved account path - browses systems - opens a game list - views details - launches a game - mobile controls respond - save/load status is shown clearly. This looks like frontend connection work, but it gets inconsistent when every Figma frame is treated as a separate screen. WebView game behavior can lead to unexpected results in real use, so I handle it by starting with a screen inventory and then testing the actual Android APK flow. The part to get right early is the game launch path, because it affects usability, correctness, and future iOS release planning.

Hi, I’m a front-end game developer with strong experience building interactive apps that bridge UI, gameplay, and real backend systems. I’ve worked extensively with React-based stacks, mobile packaging, and game-oriented interfaces, so this kind of hybrid “app + playable content” project fits perfectly with what I do. I’ve handled similar workflows end-to-end: translating Figma into structured, reusable UI systems (not just static screens), connecting REST APIs, and making everything run smoothly inside mobile environments using tools like Capacitor and WebView. I’m comfortable defining a clean screen/component architecture first (separating real screens, states, modals, etc.), then wiring everything to the backend while keeping performance and UX tight, especially important for game browsing, launching flows, and input handling. On top of that, I’ve built Android APKs for testing and set up projects in a way that keeps the path open for iOS later, avoiding platform-specific dead ends. Debugging WebView quirks, handling loading/error states properly, and ensuring responsive behavior across devices are all things I deal with regularly. My background in front-end game dev also helps when integrating things like emulator views or interactive players. If this sounds aligned, I’d be happy to review the Figma and backend structure with you, propose a clear screen get a working APK in your hands quickly. Let’s get this first version solid and set you up for the next apps as well

⭐⭐⭐⭐⭐ ✅Hi there, hope you are doing well! I have successfully connected React-based frontends to backend APIs in mobile apps before, enabling seamless user experiences with responsive UI and live data. From my experience, the most crucial part of this project is ensuring smooth API integration combined with proper packaging for Android APK while keeping the path open for iOS support. Approach: ⭕ Review your existing frontend foundation and Figma files (post NDA) to categorize all screens, states, and components. ⭕ Connect real backend REST APIs to frontend screens to enable full app functionality like browsing games, launching, login, and saving progress. ⭕ Polish the app flow ensuring all loading, empty, and error states are handled cleanly. ⭕ Build and test an Android APK using Capacitor or Android WebView. ⭕ Provide complete build instructions, report on any API issues, prepare QA checklist, and recommend iOS build strategy. ❓ ❓ Could you please share the current frontend tech stack details and backend API documentation availability? ❓ Do you have any preferences for the iOS build approach (Capacitor or other)? I am confident I can deliver a solid Android APK connecting your retro gaming app frontend and backend efficiently and prepare it for future iOS release smoothly. Looking forward to working with you!

Hi, I caught the detail that your Figma file includes many non‑screens like button states and modal variations, so getting a clean screen inventory is the logical first milestone. I've handled similar React/Next gaming interfaces before, including one where I delivered a full Capacitor-based build that bundled EmulatorJS and produced stable Android APKs. In projects like this, the real complexity isn’t UI layout, it’s mapping every UI state to real API behavior while keeping the WebView environment predictable. The risk is inconsistent navigation or broken game-launch flows if the backend contracts aren’t clearly surfaced, so I keep a tight integration log from day one. I’ll connect your existing frontend to the APIs, define reusable components, implement the navigation flow, and package the app as an Android APK via Capacitor while keeping the architecture clean for a future iOS build. Before starting, I’ll need clarity on API response shape, any auth edge cases, and your current build pipeline so I can align the integrations cleanly. I’ll deliver a working APK and the documentation you requested. Thanks, John allen.

Hello, The primary engineering challenge lies in ensuring seamless API integration with the existing backend while maintaining responsive UI interactions. Another concern is establishing a robust architecture that supports both Android and future iOS releases without introducing platform-specific constraints. Could you clarify the expected real-time functionality for user interactions, such as game progress or account updates? Additionally, what specific backend endpoints are available, and are there any anticipated limitations or missing fields we should address during development? Looking forward to discussing the architecture and your vision for the app.
