Worked on updating the aiven/aiven-docs repository to clarify service plan downgrade rules for Aiven for ClickHouse, focusing on improving documentation accuracy and user guidance. Used Markdown to revise policy descriptions, ensuring that users understand node reduction is only possible by switching from Business to Startup plans on running services, not by forking to smaller clusters. Collaborated with product teams to align documentation with actual product capabilities, reducing ambiguity and potential support queries. Demonstrated strong documentation skills and attention to detail, contributing to smoother onboarding and more consistent customer experiences by explicitly reflecting plan downgrade policies in the official documentation.
