The brief

The challenge

ZetaCADD is an engineering design studio in Ahmedabad, India, that has produced CAD drawings for manufacturers in Europe, the USA, Canada, Australia and New Zealand for more than 15 years. The business was moving to a new name, ZetaCore, and a new domain, and its website was a WordPress build on Elementor, a stock theme and a slider plugin. On a mobile Lighthouse test the old homepage scored 57 for performance, weighed 2.4 MB and took 16.4 seconds to show its main content. For a studio that sells precision, the new site needed to look like engineering work and load like it too.

Our approach

What we built

We designed the site around the way ZetaCore delivers its work: as checked, numbered drawing sheets. The homepage hero is an isometric flanged bearing unit you can click to explode and reassemble, the portfolio is presented as issued sheets with a full-size drawing-sheet lightbox, and the FAQ reads as an RFI log. Live clocks show the working-hours overlap with London, New York, Vancouver, Sydney and Auckland. Underneath, the site is built in Next.js 16 with every page pre-rendered: four services and sixteen sub-services generated from one data source, insight articles, a careers section where candidates apply on the page, and an enquiry form that reaches the team directly. We moved the real portfolio, testimonials and contact details across from zetacadd.com, carried the new name and mark through every page, and added structured data, an llms.txt for AI answer engines and Open Graph images. The drawings animate, but pause while off screen, so they never slow the page down.
