• Financial and cosmetic economy. Take point on implementing currencies, balances, drops, crafting, cosmetics and entitlements, including reconciliation with on-chain assets and commerce. Every transaction must be idempotent, auditable and reversible.
• Social product. Chat, timelines, feeds and notifications, built as reusable backend capabilities rather than one-off features. rather than one-off features.
• API model. Implement contract-first, versioned APIs, and help evolve the contracts with the architect so frontends, mobile and third-party clients can build on them.
