Worked on the MicrosoftDocs/azure-ai-docs repository, focusing on enhancing documentation quality and security over a two-month period. Improved the clarity and discoverability of the prompt-engineering.md file by restructuring title elements and updating metadata, aligning with Azure AI documentation standards. In a separate update, replaced hardcoded API keys in assistant-functions.md with environment variable placeholders to mitigate credential exposure risks in public examples. All changes were non-code, emphasizing documentation best practices and secure-by-default guidance. Utilized Markdown for all documentation updates, demonstrating attention to detail and a methodical approach to maintaining high standards in technical writing and documentation management.
