BookBix
BookBix is a modern book marketplace platform that allows users to buy, sell, and trade books. The platform features secure payment processing, user authentication, and a responsive interface for browsing and managing book listings.
My Role
As a Backend Developer on this project, I was responsible for designing and implementing core backend services using NestJS and MongoDB. My primary focus areas were the payment processing system with Stripe integration and the JWT authentication system to ensure secure user sessions and data protection.
Development Process
Our team of 9 followed Scrum methodology, with regular sprint planning sessions to define tasks and priorities, daily standups to track progress and address blockers, and sprint reviews to demonstrate completed features and gather feedback. This structured approach helped us maintain consistent progress and adapt to changing requirements throughout the development process.
Technical Implementation
For the payment system, I integrated Stripe API to handle secure transactions, including features like payment intents, webhooks for transaction status updates, and refund handling. The authentication system used JWT tokens with refresh/access token strategy to maintain secure sessions while providing a smooth user experience.
