Web Application Performance Optimisation
For organisations where slow applications are costing money or users.
End-to-end performance audit and hands-on remediation across the full stack: frontend, backend, infrastructure, and data fetching. I find the problem wherever it lives, not just where it's easy to look.
Sound familiar?
- Your app is slow and you're losing users or conversions because of it
- Core Web Vitals are failing and hurting your search ranking
- Pages feel fine in development but crawl under real load
- You've optimised the frontend but the bottleneck is somewhere else
- Performance regressed over time and nobody owns fixing it
- Slow response times are starting to cost real revenue
What's included
- Core Web Vitals optimisation (LCP, INP, CLS)
- Bundle analysis, code splitting, and caching strategy
- API and database query analysis
- Rendering strategy review (SSR, SSG, ISR, client-side)
- Load testing and resilience review
- Prioritised remediation plan, or hands-on delivery

Common questions
My frontend is already optimised. Can you still help?
Usually, yes. When the frontend is tuned and things are still slow, the bottleneck is normally further back: API design, database queries, rendering strategy, or caching. I audit the full stack and find the problem wherever it actually lives.
Will this improve my Core Web Vitals and SEO?
Core Web Vitals (LCP, INP, CLS) are a core part of the work, and improving them helps both user experience and search ranking. I measure before and after so the improvement is evidenced, not assumed.
Do you just advise, or actually fix it?
Both are available. Some clients want a prioritised plan their team can execute; others want me to do the hands-on remediation. The end-to-end option covers audit through to implementation.
How do you measure success?
Against real metrics: Core Web Vitals, load and response times, and where relevant, conversion or engagement. We agree what good looks like up front so the result is objective.
What does it cost?
Every engagement is fixed-scope and quoted after a short review of your application, so you know the cost before any work starts. It depends on the size of the application and how much you want me to fix versus report on.
