Performance Optimisation
A slow site quietly costs you customers, and you never find out which ones.
Why this
matters.
People do not complain that a site is slow, they just leave. If your page takes more than a few seconds, most visitors are gone before they see anything you paid to put there.
It matters more here than most places. A lot of South Africans browse on mobile data with a weak signal, so a site that feels fine on your laptop can be unusable to the customer standing in a queue somewhere.
The important bits.
01
Images that are not the problem
Modern formats, correct sizes and lazy loading. Oversized images are the single most common cause of a slow site.
02
Core Web Vitals
LCP, CLS and INP brought into the green, which is what Google actually measures your site against.
03
Less to download
Code splitting, unused scripts removed, and rendering strategies that send less work to the browser.
04
Proven, not promised
Measured before and after with the same method, so you can see the improvement rather than take my word for it.
What I work on
- Image compression and modern formats
- Code splitting and lazy loading
- Server-side rendering and static generation
- Browser and CDN caching
- Removing render-blocking resources
- Core Web Vitals across key pages
- Database and query performance
- Third-party scripts that slow everything down
Start to finish.
Measure first
I test the site properly and find what is actually slow, which is often not what people assume it is.
Fix the big things
Effort goes where the seconds are. Usually a handful of changes account for most of the improvement.
Measure again
Same tests, same conditions, so the difference is real and you have the numbers to prove it.
