During January 2026, Jeremie Spiesser developed a Training Data Rename API for the ansys/pysimai repository, focusing on improving the lifecycle management of training data. He designed and implemented a new API endpoint and extended the backend data model using Python and object-oriented programming principles, allowing users to rename existing training data objects without manual intervention. This feature addressed data hygiene and reference integrity issues across training pipelines, supporting better data governance and scalability. Jeremie ensured the solution was robust by incorporating unit testing and version control, delivering an end-to-end feature that enhances maintainability and future integration of data management tooling.
