My site performs well on desktop, yet mobile visitors still experience noticeable lag. I want to focus purely on loading-speed improvements, zeroing in on two pain points: heavy script loading and slow server response. The end goal is simple but strict—get First Contentful Paint consistently under 1 second on modern 4G connections. Here’s how I see the engagement playing out: • Audit: Run Lighthouse, WebPageTest or similar to pinpoint render-blocking JavaScript, inefficient bundling, and server-side bottlenecks. • Implementation: Restructure or defer scripts, fine-tune caching headers, configure HTTP/2 or QUIC where possible, and tweak server settings (NGINX/Apache, Node, or the stack you recommend). • Verification: Supply before-and-after performance reports that clearly show FCP <1 s on mobile. If we’re close but not quite there, include an actionable checklist so we can iterate quickly. Code changes will go through Git (GitHub) pull requests so I can review and test in staging before you push to production. I’m comfortable with most modern optimization techniques—Tree-shaking, code-splitting, critical CSS extraction, CDN edge rules—so feel free to use the tools you prefer. Let me know your proposed approach, key tools, and typical turnaround; then we’ll get started.
