Worked on the mdn/translated-content repository to deliver a Korean translation of the Least Privilege Security Guidelines, making essential security principles accessible to Korean-speaking developers and users. Focused on content localization and technical writing, the approach involved translating Markdown documentation while maintaining alignment with the original English source. Established a translation workflow that supports future multilingual security content and performed initial quality assurance to ensure accuracy and consistency. The work improved accessibility and comprehension of security guidance, aligning with MDN’s internationalization standards. Demonstrated skills in translation, localization, and cross-functional collaboration with security documentation teams, laying groundwork for ongoing multilingual efforts.
