Five Next.js engagements, each measured against the budget agreed at kickoff. Client names are used with permission; figures come from real-user monitoring, not lab runs. See the services behind these builds.
A legacy single-page application rebuilt on the App Router with server components and edge caching. Bounce rate fell 42% and interaction-to-next-paint improved 110%.
A headless CMS build with a bespoke scroll-driven motion system. Perfect Lighthouse scores across performance, accessibility, and best practices without cutting the art direction.
A realtime operations console rendering 40,000 concurrent rows with virtualisation, optimistic mutations, and an explicit state machine for dispatch conflicts.
A token-driven component library adopted by four product teams, documented to WCAG 2.2 AA with composition rules that removed the need for design review on routine screens.
A performance rescue on an existing Next.js estate: payload cut from 1.4mb to 108kb on first load, with CI budgets that have held for eighteen months.
We run two engagements at a time. Tell us what you are building, or price it yourself first — the calculator is honest about ranges.
