Backend & Accounts: Lightweight backend (Firebase / Supabase or Node.js) handling user authentication, profile ratings, game state saving, and analytics.

Monetization Architecture: Integration of RevenueCat / Stripe / Google Play & Apple In-App Purchases for subscriptions or cosmetic unlocks.

Required Qualifications:

Proven experience integrating chess libraries (chess.js, Stockfish engine, or WebSockets for real-time play).

Clean code architecture with clear documentation and source code handoff.

Budget & Milestones:
