Worked on backend reliability for the ZoeyVid/NPMplus repository, focusing on resolving a recurring HTTP 500 error affecting the Stream List page. Addressed the issue by replacing integer type casting with direct string comparison for the incoming_port field, which eliminated type-related server crashes and improved stability under load. The solution was implemented in JavaScript, leveraging backend development skills to ensure type-safe handling and consistent query behavior. The patch was delivered as a targeted code change, validated through CI and staging environments, and deployed to production with minimal risk, resulting in a smoother user experience and reduced support incidents for Stream List queries.
