Worked on the GSA/open-gsa-redesign repository to update documentation and user guidance related to the deprecation of the Legacy Rates API. Focused on improving communications by implementing a Markdown-based deprecation banner within the API documentation and user interface, clearly indicating the API’s retirement and directing users to the CALC+ platform and its documentation. This approach aimed to reduce confusion for developers and integrators during the transition period. The work centered on documentation skills and effective use of Markdown to ensure clarity and accessibility, with no bug fixes required during the period and a single feature delivered to support the transition plan.
