Core Web Vitals & Frontend Performance

For marketing sites and React/Gatsby builds where speed affects SEO and conversion, I turn LCP (Largest Contentful Paint), INP (Interaction to Next Paint), and CLS (Cumulative Layout Shift) issues into a prioritized implementation plan and measurable gains.

§ 05 · FAQ

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.
