intelligent-cache
by dadbodgeoff
Multi-layer caching with type-specific TTLs, get-or-generate pattern, memory and database layers, and graceful invalidation without cache stampede.
caching-strategies
by dadbodgeoff
Implement multi-layer caching with Redis, in-memory, and HTTP caching. Covers cache invalidation, stampede prevention, and cache-aside patterns.
performance-optimization
by jankneumann
Optimizes application performance with the MEASURE → IDENTIFY → FIX → VERIFY → GUARD workflow. Covers frontend Core Web Vitals (LCP ≤ 2.5s, INP ≤ 200ms, CLS ≤ 0.1), bundle budgets, and React re-render hygiene, PLUS backend latency budgets, Postgres/MySQL EXPLAIN ANALYZE workflows, N+1 query detection, connection-pool sizing, and async profiling with py-spy / cProfile. Use when performance requirements exist, when Core Web Vitals or p95 latency miss thresholds, or when profiling reveals bottlenecks that need fixing.
