Worked on the ansys/pyhps repository to enhance reliability and maintainability of the file download workflow. Focused on backend development and API reliability, the main contribution involved fixing a bug that ensured downloaded files retained their original filenames, directly addressing user experience and support concerns. Implemented a regression test using Python to safeguard against future issues, integrating this into the continuous integration pipeline for ongoing quality assurance. Emphasized unit testing and a test-driven approach to maintain code quality. No new features were introduced during this period, as the priority was on stability, consistency, and improving test coverage within the existing system.
