Performance skills
Rendering, caching, and runtime optimization for fast interfaces.
nextjs-api-performance
Audits and optimizes Next.js App Router APIs using measured request timing, cookie-first authentication, Server Component prefetching, PostgreSQL query tuning, Drizzle transaction patterns, caching, and durable background work. Use when API routes, server rendering, database queries, authentication, mutations, or loading UX are slow.
optimistic-cache-pattern
Instant UI with background data resolution using React Query cache layers. Apply when building CRUD UIs, edit forms, detail views, or any flow where partial data is already available and full data needs fetching. Eliminates perceived latency by showing what you have immediately and resolving the rest in the background.
