PetClinic

As part of the Pet Clinic project, I worked on the Cart Service implementation, focusing on integrating shopping cart functionality within the system. This involved developing the Cart microservice using Spring Boot, WebFlux, and a reactive programming approach to handle veterinary service bookings efficiently. The Cart Service enables users to add, update, and remove services from their cart while ensuring seamless synchronization with the existing Pet Clinic ecosystem. I implemented unit and integration tests using JUnit, Mockito, and WebTestClient to guarantee reliability. Additionally, I optimized the Cart API for performance, ensuring it efficiently handles multiple concurrent users.

Barbers can manage their schedules, view upcoming appointments, and track customer preferences through an integrated dashboard. The application features real-time notifications, authentication with Firebase, and secure payment options, ensuring a smooth and reliable booking experience. To enhance performance and scalability, I implemented MVVM architecture with a Room database for local storage and Retrofit for API communication.
