Worked on the codatio/codat-docs repository to enhance Spend Analysis documentation and user interface, focusing on clarity, consistency, and usability. Consolidated and clarified the behavior of minimum-spend filters and supplier exclusion criteria across Spend and Supplier Analysis, reducing ambiguity for end users. Standardized documentation formatting and adopted active voice throughout, improving readability and alignment with technical writing best practices. Refined the Spend Analysis UI by adjusting column widths in the Customer tab for better visual alignment and compliance with formatting guidelines. Collaborated across teams, utilizing Markdown for documentation, and applied UI/UX design and content editing skills to deliver these targeted improvements.
