Technical SEO Boost Needed

My surf-activity website is ranking lower than it should, and I have narrowed the issue down to technical SEO. I want a specialist who can audit the codebase, identify the speed bottlenecks, and implement clean, measurable fixes that move the site up in Google. Core focus • Page-load performance: compress images, optimise critical CSS/JS, fine-tune server and caching settings, and ensure Core Web Vitals all show “good” in PageSpeed Insights and Lighthouse. I am not looking for an off-page or content overhaul right now; the brief is strictly technical. Once your work is complete, I expect: 1. Before-and-after speed metrics (mobile and desktop). 2. A concise changelog of every optimisation applied. 3. Confirmation that there are no new console errors, broken links or mobile-usability warnings in Search Console. If you can deliver those three items—fast—and demonstrate prior success with similar optimisation projects, let’s get started.
