E‑commerce site using GraphQL + React + SSR shows 20s first‑load per Speed Insights and a Lighthouse score in the single digits; team uses DataDog APM to find slow resolvers, then: trim bundles and add lazy‑loading, set proper HTML cache headers and separate user‑specific fragments, fix GraphQL N+1 by batching/resolving server side and use fragment co‑location to stop over‑fetching. Result: page load and score improve to roughly the high 40s; work continues.
