When a project needs a fully custom frontend — not a page builder — I build it with Next.js and the App Router: server components, server actions, and the SSR/SSG/ISR strategy that fits the page, so content stays fast and indexable.
The stack is TypeScript and Tailwind CSS throughout, with API routes or a full-stack setup wired in where the app needs its own backend. Core Web Vitals and SEO are treated as part of the build, not an afterthought bolted on at the end.
