You will get Next.js bugs fixed and Core Web Vitals improved
Project details
It works on localhost" and "it works in production" are two different claims. If you're seeing hydration mismatches, layout shift on load, or state that randomly resets on navigation, that's a specific, diagnosable class of problem — not a rebuild.
What you get:
Root-cause diagnosis before any fix — no guessing-and-patching that reintroduces the bug in a different form
Hydration errors traced to their actual source (usually: Date/Math.random() in render, browser-only APIs running server-side, or mismatched conditional rendering) and fixed at that source
Core Web Vitals fixes that target the actual bottleneck — oversized hero images, render-blocking fonts, unmemoized re-renders — not generic "add loading=lazy everywhere"
A written before/after report: Lighthouse scores, bundle size delta, and what changed
No breaking changes to unrelated functionality — every fix scoped and tested against your existing flows
