Chahan Kropf developed a performance-focused test optimization feature for the CLIMADA-project/climada_petals repository, targeting the TCSurgeGeoClaw module. By standardizing the centroid resolution parameter in tests to 0.1, Chahan streamlined the testing process, which reduced test run times and improved continuous integration feedback cycles. The work involved Python-based test parameterization and careful adjustment of test configurations to ensure reliability and maintainability. Although no major bugs were addressed during this period, the feature enhanced development velocity for surge modeling. Chahan’s contributions demonstrated skills in software development, testing, and unit testing, with a focus on CI optimization and traceable code changes.
