DApp "Wholesale Seats" Module Development

Task Description: We are developing a community management DApp. This task involves independently developing a "Wholesale Seats" module, responsible for inventory management and transaction support for group seats/slots, as an extension of the existing payment system. Requirements: Develop a search bar and inventory display UI using React, displaying available seats by category (e.g., Crypto/Finance/Entertainment).
Integrate with MongoDB to manage inventory data (slot quantity, price, transaction status), supporting real-time updates.
Provide an interface compatible with existing USDT/USDC payment systems to simulate the seat purchase process.
Ensure the module is independent, and the API supports subsequent integration (e.g., GET/POST inventory status).
Test with 50 simulated transactions to ensure a 90% success rate (response time < 2 seconds).
Deliver via a private GitHub repository (link provided after hire, use feature branches, and submit pull requests daily).
Timeline: 1 week.
Budget: $200-250 USD
