WordPress Load Time Improvement and Edge Delivery Configuration -- 2

I want my WordPress website, especially the homepage, to load almost instantly and feel highly responsive. Over the next 30 business days, the goal is to systematically optimize every layer that influences performance. By the end of this work, I expect the following: • A properly configured caching architecture covering browser caching, full page caching, and object caching. Pages should be delivered with minimal database queries and as much content served from memory or disk as possible. You may choose the most appropriate setup, whether that involves Redis, Varnish, or a high quality caching plugin, as long as it integrates smoothly with the current theme and active plugins. • All images and media assets delivered through a CDN. I already use Cloudflare, so the implementation should take advantage of its edge network and image delivery features. If you believe another solution would offer measurable benefits, you can propose it, but Cloudflare should be treated as the primary option. • Measurable performance improvements on the homepage. Core Web Vitals should show clear gains, with Largest Contentful Paint and First Input Delay reaching green scores on both mobile and desktop environments. • Well structured technical handover documentation. At completion, I need a straightforward guide explaining the caching configuration, CDN setup, and any ongoing maintenance steps required to preserve performance over time.
