A3 — Web Development
Web Performance Optimization
Core Web Vitals, Lighthouse and CDN tuning that turns slow sites into fast ones without breaking features.
Overview
Slow pages lose visitors and can hurt search rankings, but rushed speed fixes often break features such as forms, images or tracking.
We measure where time is really lost, fix the biggest problems first, regression test every change and keep monitoring afterwards.
What we do
- 01
Measure Core Web Vitals and real-user speed
- 02
Optimise images, fonts and scripts
- 03
Tune caching, CDN and hosting
- 04
Regression test every change
- 05
Monitor speed after release
How we work
- Step 1
Scope
We agree goals, features, stack and a sprint plan.
- Step 2
Build in sprints
Weekly increments from a shared backlog, demoed as we go.
- Step 3
Test every sprint
QA tests each feature as it lands and automates the core flows.
- Step 4
Launch and support
We release, monitor and fix, and hand over code your team owns.
Who it's for
- Sites failing Core Web Vitals in Search Console
- Stores and SaaS sites with slow key pages
- Teams whose past speed fixes broke something
What you get
- A performance baseline
- Optimisations to code, assets, caching and CDN
- Regression testing after each change
- Ongoing monitoring
Questions
Will you change our design?+
Usually not. Most speed improvements happen behind the scenes; if a design change would help, we'll explain the trade-off first.
Which platforms do you optimise?+
Custom React and Next.js sites, WordPress, Shopify and most common platforms.
How quickly can you start?+
Most engagements start within 5–7 business days of agreeing scope, and urgent work can start within 48 hours.
