Worked on performance hardening for the streamlit/streamlit repository by implementing static asset cache optimization. Focused on backend development and web server configuration, the approach involved configuring Cache-Control headers with explicit max-age and immutable directives for hashed static assets, while deliberately excluding HTML files and manifest.json from long-term caching. This strategy, executed in Python, aimed to reduce unnecessary network requests, accelerate initial page loads, and improve cache hit rates, ultimately lowering bandwidth usage and infrastructure costs. No major bugs were reported or fixed during this period, as the primary emphasis remained on enhancing reliability and optimizing caching strategies for better performance.
