We build marketing sites and web applications on Next.js, with a headless CMS behind them and analytics wired before the first page ships. The point is not the stack — it is that three things hold true at launch and are still true two years later: pages load in under two seconds on a mid-range phone, non-engineers can publish without a deploy, and every conversion is attributable to the page that produced it.
Speed is a feature, not a phase
Performance work bolted on at the end never survives the next quarter of feature work. We enforce a performance budget in CI from the first commit, so a change that would push Largest Contentful Paint past its ceiling fails the build rather than quietly shipping. That is why the sites we hand over are still green a year later.
- Server-rendered by default, so the first paint does not wait on JavaScript
- Images, fonts and third-party scripts budgeted individually
- Core Web Vitals measured on real traffic, not just in the lab
- A performance regression fails CI, the same as a broken test
Built for the people who edit it
A site nobody can update is a site that decays. Content models are designed around the way your team actually writes — reusable blocks, sensible constraints, previews that match production — so a campaign page takes an afternoon rather than a sprint.
Technical SEO is included, not extra
Rendering strategy, canonical handling, structured data, hreflang for multi-region sites, and an XML sitemap that reflects reality. These are architectural decisions, which is why they belong in the build rather than in a report afterwards.
