    The full UI is already designed in Figma; what I need now is a working system that mirrors those screens with a clean Angular front-end and a solid Node.js back-end. Scope • Recreate every Figma view in Angular (latest version, TypeScript and SCSS preferred) with responsive behaviour and smooth transitions. • Build a RESTful API in Node.js—Express or a comparable framework is fine—so the front-end can consume real data from day one. • Connect the two parts cleanly, setting up routing, state management and basic authentication so the project is ready for future features. Deliverables 1. Source-controlled Angular project matching the Figma layouts pixel-perfectly. 2. Node.js back-end with documented endpoints and environment-based configuration...
