Worked on backend development for the pinterest/ray repository, focusing on improving dashboard reliability by addressing a critical caching issue. Implemented a fix in Python that updated the Cache-Control header for the dashboard’s index.html file, shifting from 'no-cache' to 'no-store' to prevent clients from loading outdated content after deployments. This change ensured users always accessed the latest dashboard entry point, reducing cache-related incidents and enhancing the user experience across environments. The work demonstrated attention to deployment consistency and traceability, with clear commit and pull request references, and showcased backend engineering skills in web caching and HTTP header management.
