Revamp WhatsApp Manager UI

I already have a full source code for a WhatsApp management platform that works much like wati.io. The core features are solid, but the look and feel need a lift. My priority is a complete layout redesign focused on two key screens:

• Dashboard – clearer information hierarchy, modern visuals, responsive behaviour
• Chat Interface – cleaner message threads, better use of space, smooth interaction flow

Everything else in the system can stay as-is; the task is strictly about redesigning those interfaces and wiring the new layouts back into the existing codebase without breaking current functionality. I will share the repository and walk you through how the components are structured so you can work inside the current tech stack (React on the front-end with a Node API).

Acceptance criteria
• Refactored UI matches the new layouts we agree on (Figma or similar)
• Code integrates seamlessly; no console errors or broken routes
• Looks good on desktop and mobile breakpoints
• All existing features on the dashboard and chat screens continue to work as before

Once you deliver the updated screens and I confirm everything runs smoothly, the job is done.
