Michael worked on the chariot-giving/chariot-openapi repository, delivering an update that replaced the x-chariot-api-key header with a connect_id query parameter for filtering in the List Grants API. He focused on improving API usability and reducing client integration friction by updating both the API documentation and changelog to clarify the new behavior, especially when connect_id is omitted. Using Markdown and YAML, Michael ensured the documentation was clear and traceable, with all changes committed for transparency. While no bugs were fixed during this period, his work enhanced API consistency and maintainability, demonstrating depth in API documentation and technical communication skills.
