Performance work that users and search engines both feel

We diagnose and improve load, interactivity and stability, with changes that stick in the codebase, not one-off score chasing.

Problem

What usually breaks first

Sites accumulate heavy client JavaScript, unoptimised media and render-blocking patterns. Lab scores fluctuate while real users still wait.

Solution

How SystemNexa approaches it

We profile critical journeys, set budgets, and fix the highest-impact issues in architecture and assets. Improvements are verified against real routes, not vanity pages alone.

Capabilities

  • Core Web Vitals diagnosis
  • JavaScript and rendering strategy review
  • Image, font and asset optimisation
  • Caching and edge behaviour
  • Performance budgets for ongoing work
  • Regression checks in CI where useful

Deliverables

Typical outputs

  • Performance audit with prioritised fixes
  • Implemented optimisations on key templates
  • Budget recommendations
  • Before/after measurement notes (honest scope)

FAQ

Questions we hear often

Can you guarantee a Lighthouse score?+

No. Scores vary by device, network and third parties. We focus on meaningful improvements to real user journeys.

Do you only optimise the homepage?+

Homepages matter, but conversion and product routes often matter more. We prioritise by business impact.

Will this require a redesign?+

Not always. Many gains come from engineering and asset strategy. Visual redesign is only proposed when layout itself is the bottleneck.
