I’m planning to release a full-featured 3D mobile game and need an experienced developer who can carry it from concept to App Store and Google Play launch. The core request is a visually realistic experience—think console-quality lighting, detailed assets, and smooth animations running on modern smartphones without compromising performance. What I already have: • A high-level game concept, core mechanics, and theme. • Reference art that illustrates the visual fidelity I’m aiming for. • A rough feature list covering levels, progression, basic UI flows, and in-app purchase hooks. What I need from you: • End-to-end development in a proven mobile engine (Unity, Unreal Engine, or another tool you can justify). • Optimised 3D asset integration, lighting, and post-processing that respects mobile performance budgets. • Implementation of input, UI, save system, and analytics SDKs. • A build pipeline that outputs ready-to-publish iOS and Android packages. • Clear, well-commented code and documentation so my internal team can take over future updates. Acceptance criteria: 1. A playable vertical slice that showcases one level, core mechanics, and final-quality visuals running at a stable frame rate on mid-tier devices. 2. Source project delivered in an organised repo with build instructions. 3. Final test builds signed for TestFlight and Google internal testing, passing store compliance checks. If you have shipped at least one realistic 3D mobile title before, especially using Unity or Unreal, let’s talk timelines and your preferred workflow.
