- Design PostgreSQL schemas for marketplace, transaction, user, and blockchain data.
- Implement Redis caching and optimize database and API performance.
- Handle blockchain reorganizations, duplicate events, and on-chain/off-chain data consistency.
- Build backend services for SmartCommerce orders, payments, settlement, and fulfillment.
- Integrate IPFS/Arweave metadata with marketplace APIs.
- Write comprehensive unit and integration tests and maintain clear technical documentation.
- Build monitoring and alerting for indexer and API health.
