Developed and enhanced hyperparameter optimization workflows in the dhis2-chap/chap-core repository, focusing on backend development and data analysis using Python. Built a reusable evaluation pipeline with an updated Objective signature, new estimator retrieval methods, and metrics calculation from evaluation instances, supporting reproducibility and traceability. Introduced a searcher selection feature that enables multi-searcher support through a SearcherType enum, improving flexibility in hyperparameter optimization. Improved code quality by refining error handling, expanding unit test coverage, and tightening typing for maintainability. The work emphasized robust CI readiness, enabling faster experimentation and ensuring reliable integration of machine learning model evaluation features.
