Developed an end-to-end Vehicle Review and Rating System with user authentication for the MavithaShehar/pickn-go-backend repository, focusing on enhancing post-booking feedback capabilities. Designed and implemented secure CRUD operations for vehicle reviews, ensuring only authenticated users could create, update, or delete reviews linked to their bookings. Leveraged Express.js and Node.js to build robust API routes, incorporating input validation and authentication middleware to enforce access control. Utilized MongoDB for persistent storage of user-generated content, supporting actionable insights for product decisions. The work emphasized security and data integrity, providing a reliable backend foundation for collecting and managing user feedback within the application.
