Worked on the mdn/content repository to enhance documentation for the Performance Server Timing API, focusing on clarifying the duration property’s unit as a DOMHighResTimeStamp, which typically represents milliseconds according to W3C standards. Addressed developer confusion by updating Markdown-based documentation with explicit guidance, ensuring accurate API usage and reducing support overhead. The work demonstrated skills in API development and technical writing, with careful alignment to web performance standards. All changes were traceable to the relevant issue and commit, supporting future maintenance and auditability. No bugs were fixed during this period, with the primary contribution centered on documentation clarity and standards compliance.
