Maintained our set of reusable components, prioritized technical debt, and performed regular library and tooling upgrades.• Enabled the team to identify performance regressions and other issues by building a performance metrics dashboard to monitor load times, expensive or critical endpoint durations, and interaction delays• Optimized app load times by utilizing code-splitting and improving the critical rendering path to lower the time to First Meaningful Paint. Achieved a median Time To Interactive of < 5s for a homepage that used real-time data• Developed a declarative data-management and caching framework for the console with higher-order components. Hooks were later added and this was open-sourced as the resourcerer library• Built an API documentation SPA on the website. Combines auto-generated and handwritten documentation via a gulp task into a clean, mobile-friendly UI• Implemented a prefetching framework based on user interaction to improve "perceived performance" (blog post here: https://engineering.siftscience.com/improving-perceived-performance-by-prefetching-critical-resources/). Later added as a feature to the resourcerer library Show less
