E. Wang enhanced the MicrosoftDocs/powerquery-docs repository by updating the Databricks connector documentation to support secure OAuth M2M authentication. Focusing on technical writing and documentation skills, Wang replaced legacy Username/Password instructions with a modern OAuth M2M workflow, guiding users through the process of generating Databricks Client Credentials. The update, written in Markdown, aligns with security best practices and addresses the needs of enterprise customers migrating to safer authentication methods for Databricks SQL Warehouses. Wang’s work provided clear, actionable guidance for onboarding and support, demonstrating a focused approach to improving documentation depth and usability within a short project period.
