Looks Like This Service Is On Hold
I will speed up and optimize your slow wordpress or woocommerce website
Cao Tai L.
About this gig
Is your WordPress or WooCommerce site slow, failing Core Web Vitals, or losing visitors and sales to long load times? I make it fast.
I am a full-stack developer with 10+ years of experience in WordPress, WooCommerce, PHP and Linux servers. I optimize the whole stack, not just install a plugin, and I show you the before and after numbers.
What I optimize:
Page load time and Time to First Byte (TTFB). Core Web Vitals: LCP, CLS and INP. Image compression and next-gen formats like WebP. Caching, minification and GZIP/Brotli. Render-blocking CSS and JS and unused code. Database cleanup and slow queries. Hosting and PHP tuning where I have access.
How I work:
First, I measure your current speed with PageSpeed Insights, GTmetrix and real TTFB. Then, where possible, I optimize on a safe copy so there are no risky changes on your live site. Finally, I hand back a clear before and after report with the scores and what I changed.
I work 100% async, reply quickly, and keep clear communication. Your login details stay private and secure.
Not sure which package fits? Message me your URL first and I will run a quick check and tell you honestly.

Languages
Vietnamese, English
I'm a full-stack WordPress and WooCommerce developer with 10+ years of experience, plus the Linux/server and hosting background most WordPress freelancers don't have. I help site and store owners when something breaks or slows down: malware removal and security hardening, 500 errors and PHP fatals, broken forms and email deliverability (SPF/DKIM/DMARC), WooCommerce checkout and add-to-cart bugs, speed optimization, and zero-downtime hosting and email migrations that keep your SEO intact. I work 100% async, communicate clearly in written English, and I don't stop until the issue is solved.

FAQ
Can you guarantee a 90+ PageSpeed score?
I optimize for real speed and passing Core Web Vitals, and most sites see a big jump. The exact score depends on your theme, plugins and hosting, so I focus on measurable improvement and a genuinely faster site for real visitors.
Will optimization break my site or change the design?
No. Where possible I work on a safe copy first, take a backup, and test every change. Your design and content stay the same, only the speed improves. I tell you exactly what I changed.
What do you need from me to start?
Your site URL and WordPress admin login, plus hosting or cPanel access if server-level tuning is needed. Tell me the main pages that matter most, such as home, shop and a key product page, so I can prioritize.
