Worked on the programming-formalisms/programming_formalisms_project_summer_2025 repository to establish the foundation for a Weather Data Analysis project, focusing on project scaffolding, documentation, and requirements planning. Developed utility functions in Python, including is_odd and is_zero, with accompanying unit tests using unittest to enhance data validation and input integrity. Emphasized maintainability by creating structured documentation and risk assessments, supporting future scalability and streamlined onboarding. Applied skills in requirements engineering and test-driven development to ensure reliable feature delivery. The work prioritized clarity and governance, resulting in a repeatable process for project planning and improved code quality without addressing critical bug fixes this month.
