Jonathan Booysen - Performance-Focused UX Engineer

Hi, I'm JonnyPerformance-Focused UX Engineer

Fast sites don't guarantee conversions. I use AI-enhanced analysis to optimise performance where it actually impacts revenue - spotting friction patterns across user flows faster and proving ROI with automated measurement.

Do these sound familiar?

Users are hitting 'buy now' but abandoning before payment loads

Half your traffic is mobile and your bounce rate is 80%

Devs are fixing performance issues but conversions aren't budging

I deliver production-ready solutions that hit Core Web Vitals targets, lift conversion rates, and include the analytics to prove ROI.

Previously led interaction design and engineering teams at MultiChoice, building scalable platforms used by millions. Now I help product teams optimise performance in ways that actually move business metrics.
