During September 2025, Doh updated the CNCF TAG Developer Experience (DevEx) charter in the cncf/toc repository, focusing on refining the group’s mission, scope, goals, and out-of-scope definitions. The work centered on technical writing and documentation using Markdown, clarifying subproject boundaries and aligning the charter with CNCF TOC requirements. By restructuring the charter, Doh improved policy alignment and provided clearer guidance for cross-team collaboration, directly supporting efforts to enhance the end-to-end developer experience in cloud-native applications. The update did not involve bug fixes or code changes, but demonstrated depth in governance documentation and attention to detail in technical communication.
