Over a two-month period, contributed to the next-java-exercise repository by developing a modular Library Management System with core features for managing books, members, and borrowing workflows, as well as a multi-channel Notification System supporting Email, SMS, and Push notifications with customer discount logic. Enhanced code quality and learning by adding educational units on object-oriented design patterns such as encapsulation, builders, and singletons. Automated deployment processes by implementing a CI/CD pipeline using GitHub Actions, Docker, and Amazon ECS, reducing manual steps and improving reliability. Work was primarily delivered in Java, leveraging design patterns, AWS services, and modern development practices.
