Core Web Vitals & Frontend Performance
A structured approach to improving LCP, INP, and CLS for React and Gatsby sites focused on measurable results and maintainable implementation.
Outcomes you can expect
- Clear CWV baseline (field + lab) and a prioritized plan
- Reduced render-blocking work and faster critical rendering path
- More responsive interactions (INP) and fewer layout shifts (CLS)
- A maintainable performance budget and monitoring checklist
Deliverables
- Performance audit report (LCP / INP / CLS + supporting metrics)
- Issue backlog with severity, effort, and impact estimation
- Implementation notes (code-level guidance or PRs, depending on scope)
- Validation report with before/after measurements
Process
1) Diagnose
Collect field signals, run lab tests, and identify bottlenecks.
2) Prioritize
Rank fixes by impact, effort, and business relevance.
3) Implement & validate
Apply improvements and confirm results with consistent measurements.
Best fit for
- Marketing sites that need better speed and conversion performance
- Gatsby or React apps with heavy bundles or slow interactions
- Teams preparing a redesign, migration, or SEO-focused release
FAQ
Do you only work with Gatsby?
No. Gatsby, Next.js, and React SPAs are all supported. The approach is framework-aware but metric-driven.
How long does it take?
Audits can be delivered quickly; implementation depends on scope and access to the codebase and deployment flow.
What do you need from me?
A URL, access to analytics (if available), and optionally repository access to implement fixes.
