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 a Mongoose schema in MongoDB to capture event details, guest count, budget, and user information. Harry modularized the routing logic, separating venue quotation endpoints into dedicated files to improve code organization and future extensibility. He also integrated an auto-increment plugin to ensure unique, sequential quotation IDs. The work enhanced data integrity, maintainability, and quoting speed, reflecting a focused, well-structured approach to backend engineering.
