Build a modular node / plugin architecture (like n8n nodes) for API connectors, data operations, and logic functions.

Implement a secure sandbox for executing user-defined code / functions.

Develop RESTful APIs and WebSocket interfaces for the workflow editor (frontend).

Integrate with databases (MongoDB / Postgres) and manage workflow persistence and execution logs.

Work with Redis / BullMQ (or similar) for distributed workflow execution and queue management.

Ensure high performance, fault tolerance, and scalability across multi-tenant environments.
