Worked on the RWTH-EBC/TEASER repository to address a critical bug in threshold handling logic, specifically when with_ideal_thresholds is enabled and AHU validation is disabled. Improved backend reliability by refactoring the Python setter to assign threshold values unconditionally, which resolved a ValueError and ensured consistent behavior across configurations. Enhanced maintainability by removing obsolete tests related to AHU-threshold correspondence, streamlining the test suite and reducing future maintenance. Demonstrated backend development and testing skills through defensive coding practices and effective test management. The work focused on stabilizing production configurations and supporting robust validation for threshold-related features within the codebase.
