Frontend performance

In one line

Storefront speed/responsiveness (SSR, edge delivery) — directly tied to conversion and a core reason teams go headless.

Fuller explanation

Frontend performance — fast loads, responsive interactions via SSR frameworks (Next.js) and edge delivery (Vercel) — is directly correlated with conversion. It's a common reason enterprises adopt headless, and a tangible, measurable expansion conversation (Core Web Vitals → conversion).

Interview phrase

"Performance is a revenue feature, not an engineering vanity metric — every 100ms shows up in conversion."
