Caching & CDN Optimization

Effective caching is the single biggest performance lever for most applications — reducing database load by 90%+, cutting response times from seconds to milliseconds, and lowering infrastructure costs. We design caching architectures that maximize hit rates while solving the hardest problem: cache invalidation.

• Multi-Layer Cache Design — Architect CDN, application, and database caching layers that work together for optimal performance at every level.
• CDN Configuration — Optimize CloudFront, Cloudflare, or Vercel Edge caching with proper cache keys, TTLs, and origin shield configuration.
• Application Caching — Implement Redis-based caching with proper key design, eviction policies, and cache-aside/write-through patterns.
• Cache Invalidation — Design event-driven invalidation strategies that keep caches fresh without sacrificing hit rates or adding complexity.
• Edge Computing — Move computation closer to users with edge functions, edge-cached API responses, and geographically distributed data.
• Static Asset Optimization — Configure immutable asset caching, content hashing, image CDN, and font optimization for sub-second page loads.

We work with all major CDN providers (CloudFront, Cloudflare, Vercel Edge), Redis for application caching, Varnish for HTTP caching, and edge computing platforms. Our invalidation strategies use event-driven patterns with Kafka or webhooks for real-time cache freshness.

Applications with high latency, expensive database queries, global user bases, or high infrastructure costs from over-fetching data. Whether you need a caching strategy from scratch or want to optimize an existing setup that isn't performing, we design solutions that make measurable impact.
