I’d like to clarify a few points about the role and project setup:
1. Will the project follow a monorepo architecture or separate frontend/backend repositories?
2. Are you currently using any frameworks on Node.js (e.g., Express, NestJS) and state management tools in React (Redux, Zustand, React Query)?
3. Is the system already live and being extended/maintained, or is this a greenfield build from scratch? -

Are you looking for support on an existing application, or is this a new platform being built from the ground up?
