Real Time Bidding Game App

I want to build a real-time bidding game that runs seamlessly on both iOS and Android. The core loop is fast, head-to-head bidding rather than turn-based play, so low-latency networking and smooth state sync are critical. All visuals will be 2D; think clean, modern sprites and simple animations rather than 3D assets or retro pixel art.

The job covers the full mobile build, from lobby flow and matchmaking through to an in-game bidding arena, results screen, and basic player profile. A lightweight back-end (Firebase, Supabase, or your preferred stack) is fine as long as it reliably handles real-time events and simple leaderboards. I am open to Unity, Flutter, or any other cross-platform tool that can hit 60 fps on mid-range devices while keeping the build size reasonable.

Deliverables:
• Playable iOS and Android binaries ready for TestFlight / internal testing
• Complete, well-commented source code and asset files
• Brief setup notes so I can run the project locally and push future updates

Once the core game loop is solid, I’ll expand into additional modes and monetization, so clean, modular code matters from day one. Let me know which engine or framework you’d use, any similar real-time projects you’ve shipped, and the rough timeline you foresee for an MVP.
