During February 2026, Age worked on the mdn/translated-content repository to enhance the consistency and accuracy of XR device terminology in multilingual documentation. Focusing on content translation and documentation quality, Age standardized the spelling of 「コンピュータ」 to 「コンピューター」 throughout the XR documentation, addressing inconsistencies that could lead to user confusion and localization errors. The work involved careful review and editing of Markdown files, leveraging git-based change management to ensure traceability and quality control. This targeted update improved the reliability of localized content and reinforced documentation standards, demonstrating attention to detail and a methodical approach to terminology standardization in technical writing.
