Worked on the duckdb/duckdb-web repository to enhance documentation for the Quantile Cont function, specifically clarifying that the pos parameter accepts negative values to enable counting backwards in datasets. This update addressed a common source of user confusion and improved the onboarding experience for data analysts. The work involved careful revision of Markdown documentation, addition of usage notes and examples, and collaboration with cross-functional teams to ensure accuracy. Leveraged skills in data analysis, documentation standards, and Git version control to deliver clear, actionable guidance. No bugs were fixed during this period, with the primary focus on improving API semantics and usability.
