KAUFAST — IT services site, engineered to perform

Overview

This case study documents how KAUFAST engineered its own IT services website as a living proof of craft. A 13-locale Next.js 16 application with edge middleware, server-side rendering, and a design system built entirely in CSS — no frameworks, no bloat. Every architectural decision was made to maximize performance, accessibility, and search visibility across 156 pages.

The scope encompassed full-stack development, a bespoke CSS design system with zero framework dependencies, edge-deployed infrastructure across Vercel's global network, and an automated SEO monitoring pipeline. The result is a site that scores 97+ on Google PageSpeed while serving region-specific content to 13 markets.

The Challenge

Most agency websites are overengineered vanity projects that sacrifice performance for visual flair. We set ourselves a harder brief: serve 13 locales with locale-aware routing and region-specific content, score 97+ on Google PageSpeed across all four categories, meet WCAG 2.1 AA accessibility standards, ship structured data for every route, and deploy on a global edge network — all without a CSS framework, component library, or runtime JavaScript dependency beyond React itself.

KAUFAST — Structured Data for Every Page

"A 13-locale site with perfect Lighthouse scores, sub-100ms TTFB, and zero CSS framework dependencies — because the best showcase is the work itself."
