Prototype for AI-Powered Crypto Trading Chat Website

I'm seeking an experienced frontend developer to create a clean, modern UI-only prototype for a simple AI-powered chat website that provides crypto trading advice and insights.

At this stage, no functional features or backend development are required - just use mock data, static placeholders, or fake responses as required.

The goal is a responsive, professional-looking interface that's well-organized, component-based, and easy to connect to a backend later.

Pages / Screens to Build (All Static/Mock Data OK)

Login / Sign Up page (simple forms + option for social login placeholders)
Dashboard (overview with cards, stats placeholders, quick links to chat/account)
Chat Page (main feature – messenger-style layout with message bubbles, typing indicator placeholder, input bar, sidebar or header for crypto context)
Account / Profile Page (basic user info display, settings toggles, subscription status mockup)

Must-Have Requirements

Modern, clean, and mobile-responsive design (works well on desktop + mobile)
Use React (preferably with Next.js for better structure/performance) or similar modern stack you're highly experienced with
Well-structured, reusable components (good folder structure, component naming)
Clean, commented code that's easy for another developer to pick up later
Basic accessibility considerations (semantic HTML, keyboard navigation where sensible)
Fast-loading UI (optimize images/assets if used)

Deliverables

Full source code repository (GitHub preferred)
Running prototype (Vercel / Netlify deployment is a big plus)
Short README with setup instructions (how to run locally)

Timeline
3-4 days

Looking forward to seeing your portfolios and working with a reliable, detail-oriented developer!
Thanks!
