Worked on improving documentation reliability and accuracy across two repositories, duckdb-web and opentofu/terraform-provider-aws, with a focus on developer experience and onboarding. Addressed a SQL syntax issue in the SageMaker Lakehouse integration documentation for duckdb-web, using SQL and Markdown to prevent parsing errors and reduce support overhead. In opentofu/terraform-provider-aws, corrected a typo in the IAM policy resource documentation, ensuring alignment with actual resource behavior and facilitating faster onboarding for new users. Emphasized disciplined version control and clear commit messaging, applying technical writing and documentation skills to deliver precise, low-risk updates without impacting production code or runtime stability.
