Tao Wu enhanced the risingwavelabs/risingwave-docs repository by developing comprehensive documentation to clarify network billing and pricing for RisingWave Cloud. Focusing on Markdown and leveraging strong documentation skills, Tao detailed the billing model for public network traffic and PrivateLink, provided AWS and GCP cost breakdowns, and offered actionable guidance for cost reduction. The updates introduced network usage as a billable component for the Standard plan, directly addressing customer needs for price transparency and improved budgeting. Tao’s work demonstrated depth in understanding cloud billing complexities and translated them into clear, maintainable documentation, supporting both technical and non-technical stakeholders in cost management.
