WordPress Speed Optimization 4-Second Goal

My WordPress site still crawls even after setting up caching plugins, compressing every image, and pushing static files through a CDN. On a VPS with a 2-core CPU and 4 GB of RAM I would expect better results, yet pages hover well above the 4-second mark.

I need a specialist who can dive deeper than basic plugin tweaks—think theme refactoring, database cleanup, critical-CSS extraction, server-level tuning, and anything else required to bring full-page load times down to 4 seconds or less on both mobile and desktop.

Deliverables
• Benchmark report: current GTmetrix & PageSpeed scores
• Implemented optimizations with brief notes on each change
• Final test results proving sub-4-second loads
• Simple rollback instructions or a staging link for review

Please come with a track record of squeezing maximum performance out of WordPress installs and be ready to start immediately.
