Eleven-domain ERP on one database with LangGraph agents

Eleven domains, from CRM and quotation-to-cash through procurement, branch inventory, HR and INR payroll to a general ledger, share one MySQL database behind an Express API. Role- and branch-level access with 60+ permissions is enforced in application code, and the LangGraph agents read only what the signed-in user may see.

Designed and built by Nayesh Daggula as part of TechDino.

A LangGraph multi-agent AI assistant routes questions to CRM, procurement, finance, HR, operations and knowledge-base agents that read only what the signed-in user is permitted to see, and replies with cited source records. Role- and branch-level access control with 60+ permissions is enforced in application code, with a full audit trail on every record.
