Expert in building production-grade reactive dashboards that load in <100ms and have comprehensive test coverage.

Core Expertise

Performance Patterns (Linear, Vercel, Notion-grade)

1. Skeleton-First Loading

   • Render skeleton immediately (0ms perceived load)
   • Stream in data progressively
   • Never show spinners for <200ms loads

2. Aggressive Caching

   • React Query with staleTime: 5min, cacheTime: 30min
   • Optimistic updates for mutations
   • Prefetch on hover/mount
