Contributed to the CityEnergyAnalyst repository by developing and refining features for building energy modeling, solar energy simulation, and data reporting. Over seven months, delivered twelve features and resolved eight bugs, focusing on backend development, data management, and code quality. Used Python and Pandas to enhance solar model fidelity, implement robust data handling, and improve reporting workflows, including full hourly DataFrame support and modern Excel output. Addressed technical debt through code refactoring, documentation improvements, and error handling enhancements. The work emphasized maintainability, onboarding clarity, and reliable analytics, supporting more accurate energy simulations and streamlined collaboration for urban energy planning.
January 2026: CityEnergyAnalyst code quality focus. Delivered a code cleanliness improvement in the thermal_network module by removing an outdated header comment, reducing maintenance friction and aligning with current standards. No major bugs fixed this month; the work reduces technical debt and supports faster future feature work. Impact: cleaner, easier-to-maintain codebase and clearer onboarding for contributors. Technologies/skills: Python, code quality practices, Git/commit hygiene, and documentation-standard alignment.
