The problem

What you're seeing

Mobile Lighthouse scores are 30+ points behind desktop and users on 4G see a blank screen for too long.

How we fix it

Our approach

We profile on real mid-tier Android devices, ship a mobile-first JS budget, and optimise the critical render path. Mobile parity with desktop within a sprint.

Concrete deliverables, no fluff

Every engagement ends with measurable, documented outcomes — no black-box agency reports.

  • RUM-driven audit with line-level fix list

  • Implementation of every critical fix

  • Before/after metrics with screenshots

  • CI performance gate to prevent regression

Industry-standard stack, no proprietary lock-in
