My site runs on an Emergent AI-powered stack, and the core build is finished, but the experience still feels rough around the edges. I need a developer-designer hybrid who can polish the user interface and remove the little performance hiccups that are holding us back. First, the look and feel: update the layouts, refine component spacing, tighten visual hierarchy, and generally make the interface intuitive and modern without rewriting the whole front-end from scratch. Keep the existing brand assets; everything else is open to improvement as long as the result is clean and accessible. At the same time, I expect tangible performance gains. I’d like to end up with: • noticeably faster loading speed (sub-2-second first paint on desktop and mobile) • flawless mobile responsiveness across recent iOS and Android devices • server-side efficiency tweaks that shave processing time and cut resource usage, with a short before/after report You’re free to use whatever tooling you prefer—React, Vue, vanilla JS, CSS frameworks, Lighthouse audits, CDN configuration, server-level caching—so long as the final site ships fast and looks sharp. When you deliver: push the updated UI to my Git repo, document the key code changes, and supply a quick performance benchmark that proves the improvements. If everything checks out, I’ll merge and roll it live immediately.
