PetHaven is a feature-rich, multi-role web application developed using Java Spring Boot for the backend, React.js for the frontend, and MySQL as the database. It is designed to provide a seamless digital adoption, selling, and delivery experience for various stakeholders—Admins, Shelters (Sellers), Adopters (Buyers), and Delivery Partners—each with distinct roles and functionalities. The platform enables shelters to register, manage adoptable pets with multiple images, track adoption requests, run live pet auctions or supply auctions, handle inventory of pet supplies, and view adopter feedback. Adopters can register, search for pets or supplies using voice or filters, add adoption kits to their cart, place and track adoption requests or orders, make payments via UPI/CARD/COD, write reviews, and request returns for supplies. Admins manage shelter approvals, pet categories and breeds, adopters, pets, delivery partners, adoption/deliver assignment, and payments. Delivery partners register with necessary documents, get approved by the admin, and update the delivery status of assigned adoption kits or supplies. The inclusion of features like real-time auction bidding for pet supplies or adoption sponsorships, voice-based pet/supply search, structured return/refund tracking for supplies, and admin-controlled delivery assignment distinguishes PetHaven as a dynamic and modern pet adoption platform tailored for efficiency, convenience, and scalability.
