How do you improve performance across both frontend and backend?
Answer
Performance is end-to-end.
**Frontend:** reduce JS, optimize images, improve Web Vitals.
**Backend:** optimize queries, cache hot reads, tune concurrency, reduce payload sizes.
**Network:** use CDN, compression, HTTP/2/3, keep APIs lean.
Measure first (RUM + APM) and optimize the biggest bottleneck, not the easiest change.
