Harry Raj developed a robust Venue Quotations API for the EventoryHost/Eventory-backend repository, focusing on scalable quoting workflows for event vendors and organizers. He designed and implemented new API endpoints using Express.js and Node.js, with MongoDB and Mongoose managing data persistence. The solution introduced a dedicated Mongoose schema to capture event details, guest counts, budgets, and vendor information, while integrating an auto-increment plugin to ensure unique, sequential quotation IDs. By modularizing the routing logic into separate files and updating the main API index, Harry improved code organization and maintainability, laying a foundation for future extensibility and streamlined vendor quotation management.
