Project description:
You will be responsible for developing a completely new frontend layer based on approved Figma designs while preserving the existing backend, business logic, and integration services.
The application follows a decoupled architecture where the frontend communicates with backend services via REST APIs, with potential future support for WebSocket and SSE communication. The current frontend implementation will remain available as a reference point to support integration and ensure feature parity where required.
You will work alongside an experienced client-side development team, including Frontend Engineers and a Team Lead, while QA activities are handled by the client.
