Esmira Mikail established the foundational architecture for the B39_GRB3_JAVA_TAKS repository, focusing on scaffolding for an upcoming Odd/Even determination feature. She created the Esmira package and introduced a placeholder Week1OddOrEven class, setting up clear module boundaries to support future Java development. By emphasizing maintainability and modularity, Esmira ensured the codebase would be easy to extend in subsequent sprints. Her work involved structuring the repository for traceability and preparing it for additional features, leveraging her skills in Java and software architecture. Although the initial phase did not include bug fixes, her contributions laid essential groundwork for future implementation.
