Web Performance Optimisation
Slow web applications lose users and rank lower in search results. Praxis diagnoses and fixes performance problems in React and Next.js applications — from Core Web Vitals and frontend rendering to database query performance and server response times.
Core Web Vitals
LCP, CLS, INP, and TTFB — the metrics that affect both user experience and Google search ranking. Praxis identifies the specific causes of poor scores and fixes them: image optimisation, font loading, JavaScript bundle size, layout shifts, and server response time.
Database and backend performance
Slow pages are often caused by slow queries, not slow frontend code. Praxis identifies N+1 query problems, missing indexes, expensive joins, and unoptimised data access patterns — and fixes them at the source.
Measurable improvement
Before-and-after metrics for every change. Lighthouse scores, Web Vitals field data, and query execution times — documented so you can see what improved and by how much.
question
Our Lighthouse score is poor. Can you fix it?
Yes. Praxis runs a full performance audit, identifies the specific causes of poor scores, and implements fixes. Lighthouse score improvements are measurable and documented.
question
Our app feels slow but Lighthouse looks fine. Can you help?
Yes. Lighthouse measures initial load. Runtime performance — interactions, data fetching, state updates — requires different diagnostics. Praxis covers both.
