Kang Kang developed the Pyokemon Notification System for the Team-OTwo/pyokemon-service repository, delivering a scalable, real-time notification pipeline that streamlines user engagement. Leveraging Java, Spring Boot, and Kafka, Kang designed and implemented a dedicated notification module with integrated database schema and Docker-based configuration for production readiness. The system processes booking and event data into user-facing notifications, utilizing Firebase Cloud Messaging for delivery and Kafka for reliable event-driven processing. Kang completed comprehensive end-to-end tests, including notification viewing, marking as read, and bulk sending, ensuring robust functionality. This work established a strong foundation for automated, event-enriched notifications within the service.
