Same design, new engine: a pure performance rescue.
The baseline models a site whose owner already paid for a design they like — shipped on a bloated theme that fails every speed test. The rebuild keeps the design pixel-for-pixel and replaces everything underneath.
A rebuild study: a typical underperforming website, rebuilt to our standard under a fictional brand. The engineering is real — every number is measured on the build.

The starting point
This is the most common rescue case we see: a recent redesign the owner likes, built on a heavy theme — 4MB of JavaScript, a 6.8-second mobile load, failing Core Web Vitals across the board. A second full redesign would be neither affordable nor necessary. The design isn't the problem; the construction is.
The rebuild
We rebuilt the templates in clean code while preserving the approved design exactly: same layout, same colors, same imagery. JavaScript shipped to visitors dropped by 90%, images were properly sized and lazy-loaded, and hosting moved to an edge network.
Four weeks, no visual change, no downtime — and a 6.8-second load became 1.0 seconds.
What it demonstrates
Speed is separable from design. When the look is fine and the engine is broken, we replace the engine — this build shows exactly how much headroom that recovers, with before-and-after numbers measured under identical lab conditions.
