Worked on the SJSU-CS-systems-group/DDD repository, delivering a dependency management refactor for DDD-signal-protocol-java. The work involved removing SessionCipher.java and introducing lib-signal-protocol as a local Maven artifact, which streamlined the build process and improved modularization. By leveraging Java and XML within the Maven ecosystem, the changes reduced coupling between DDD and the signal protocol component, enabling faster continuous integration and laying the foundation for independent artifact versioning and offline builds. This refactor focused on dependency management and modular design, providing a maintainable structure for future development while enhancing build efficiency and simplifying artifact handling.
