About this gig
A white-screen error or a site that fails Core Web Vitals doesn't just look bad it costs you Google rankings, conversions, and visitors who leave before the page even loads. And if your site isn't accessible, you're quietly locking out real users while risking compliance issues too.
I fix WordPress critical errors, optimize Core Web Vitals for real PageSpeed scores, and bring your site up to WCAG accessibility standards three problems most sites have and most fixes ignore.
What you get:
- Critical errors diagnosed and fixed at the root, not just patched
- Real Core Web Vitals improvement (LCP, CLS, INP) not fake caching tricks
- WCAG accessibility fixes so your site works for every visitor
- Before/after reports so you see exactly what improved
- Clean, stable site that stays fixed after delivery
Whether your site is completely down, painfully slow, or needs to meet accessibility standards, I diagnose the actual cause instead of guessing with generic plugins.
Send me your site URL and what's happening I'll tell you exactly what's wrong before you order.
