About this gig

When a previous developer leaves you with something slow or unstable, the instinct is "let's rebuild it." Usually that's not necessary the fix is a proper audit and targeted repairs.

I profile with Chrome DevTools and Lighthouse and read the actual codebase, not just the symptoms. Standard and Premium include a written findings report before any fixes begin.

What you get:

  • Full audit: rendering strategy (SSR/SSG/ISR), bundle size, image handling, unnecessary re-renders, slow database queries
  • Written report of what's actually wrong (Standard/Premium)
  • Fixes based on the audit
  • Before/after Lighthouse comparison


I won't promise a specific Lighthouse number upfront that depends on hosting and third-party scripts too. I'll tell you honestly what's realistic after the audit.
