Worked on improving technical documentation quality and accuracy across open-source repositories, focusing on apache/doris-website and scala/docs.scala-lang. Addressed user onboarding and support challenges by fixing SQL syntax errors, updating configuration defaults, and correcting terminology in multilingual docs. Used Markdown to implement targeted bug fixes, such as resolving formatting issues in materialized view synchronization guides and updating FE-config documentation to reflect new default values with version notes. Enhanced the Chinese Scala reflection documentation by correcting terminology, ensuring consistency for non-English readers. Prioritized clarity, repository standards, and user comprehension, delivering low-risk, high-impact documentation improvements that support reliable usage and reduce confusion.
