I run a React-based site whose first priority is page performance and loading speed. The JavaScript and CSS bundles are bloated, the text-to-HTML ratio is poor, and several resources are still blocking crawlers. I want the site trimmed, tuned and measured against Lighthouse and Core Web Vitals before we turn to the broader SEO work. After the performance pass, I’ll need the following delivered: • Proper title, meta description, canonical, Open Graph and H1 tags on every page • A secure “forgot / reset password” flow in the admin panel • Robots.txt adjusted so nothing vital is blocked from crawling • HSTS enabled across all sub-domains with the header verified in security scans Acceptance criteria: at least a 40 % reduction in bundle size, First Contentful Paint under 2.5 s on desktop, meta tags visible in page source, password reset emails functioning in both staging and production, no crawl errors in Search Console, and a clean HSTS report. Tell me how you plan to refactor the existing React build—whether you prefer Webpack, Vite or another approach—and how long you’ll need for the first speed pass. Repo and staging access are ready as soon as we agree.
