From 22 seconds to 3.3 on a phone

A bionics company’s site full of 3D hand renders, autoplay video and scroll animation. Rebuilt how it loads, not how it looks: main content on a phone in 3.3 seconds instead of 22, and every page readable by Google.

The case
01 · The problem

Eight megabytes before anything moved.

The homepage downloaded about 8 MB and 280 files before it settled: eight YouTube players, hundreds of animation frames for the 3D hand, a 725 KB decorative background. The server took over a second to build each page. On a mid-range phone the main content showed after 22 seconds.

02 · What I changed

Five fixes, design untouched.

A hard constraint from the client: the design and page structure stay exactly as they are. Everything happened under the hood, each fix measured against the original site in the same environment. The bars show roughly how much of the homepage weight was left after each step.

03 · The result

Same design. Seen six times sooner.

Main content on a phone in 3.3 seconds. Lighthouse performance from 56 to 90 on the homepage, 58 to 94 on the prosthetics page, with the renders, videos and scroll animations exactly as before. On the live server, page generation dropped from about 1.3 s to 0.2–0.5 s.
