KAUFAST — IT services site, engineered to perform

Overview

We built our own website as a living case study. 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 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.

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