Emily Le contributed to the MicrosoftDocs/powerquery-docs repository by enhancing documentation for Power BI connectors, focusing on authentication and driver integration. She updated the Delta Sharing connector documentation to include OAuth (OpenID Connect) alongside Bearer Token authentication, providing clear guidance for both methods and reducing onboarding errors. In addition, Emily delivered comprehensive documentation for the Arrow Database Connectivity (ADBC) driver in Databricks connectors, detailing preview workflows and improving navigation accuracy. Her work involved technical writing, API integration, and Markdown, with careful attention to documentation correctness and user guidance, resulting in more reliable onboarding and reduced support friction for connector users.
