I’m planning to launch a new mobile game and need an experienced developer who can deliver a single code-base build that ships smoothly to both iOS and Android. The concept and art are in place; what I’m missing is a professional who can translate them into a polished, store-ready application with solid performance on a range of devices. Unity, Unreal Engine, Flutter with Flame, or another proven cross-platform framework is fine—as long as the end result meets App Store and Google Play requirements for speed, stability, and compliance. In your reply, focus on the relevant experience you have releasing games on both platforms. Screenshots, live links, or a short breakdown of your most similar projects will help me gauge fit quickly. Key expectations • Single code-base targeting iOS + Android • App Store / Google Play submission support • Integrated ads or in-app purchases (if you’ve done this before, highlight it) • Clear milestone plan from prototype to launch Once we agree on scope, I’ll share gameplay flow, artwork, and any APIs you’ll need.

A few quick questions to get us started: 1. Which genre/gameplay style are you targeting, and do you have a game design doc? 2. Single-player, multiplayer, or both? 3. Which platforms — Android, iOS, or both — and do you need monetization (ads/IAP)? Thanks & Regards, Deepak

Hi, Your project is well planned and having the game concept and artwork ready means we can focus entirely on building a polished, high-performance product. I can develop the game using a single cross-platform codebase, ensuring consistent gameplay and optimized performance across both iOS and Android while keeping the project easy to maintain and expand. I'll follow a structured milestone approach: gameplay implementation, core mechanics, UI integration, optimization across devices, testing, and finally App Store & Google Play submission support. If monetization is required, I can also integrate ads or in-app purchases using scalable, maintainable architecture. Throughout development, I prioritize clean code, responsive gameplay, efficient memory usage, and store compliance to minimize issues during review and publication. A couple of questions: * Which engine or framework do you prefer (Unity, Unreal, Flutter/Flame), or would you like my recommendation based on the game type? * Will the game include online features such as leaderboards or multiplayer, or is it entirely offline? I'd be happy to discuss the gameplay flow once you share the assets and requirements. Looking forward to working with you!

The fact that concept and art are already done puts this in a strong starting position. That's usually the bottleneck. I'll build this in React Native with a game engine layer, or Flutter with Flame depending on your gameplay complexity. I've shipped apps to both stores and handled the full submission process including compliance tweaks Apple tends to flag on first review. I'll take it from prototype through a polished, store-ready build with ad integration (AdMob) and in-app purchase setup for both platforms. One thing worth noting early: Apple now requires a privacy nutrition label that accounts for every SDK, including ad networks. Missing it is the most common rejection reason for indie games, so I'll handle that from day one. 1) What's the gameplay style, is it casual/2D or does it involve any 3D rendering? Happy to talk details in chat. Shayan
