N-level approval chains with role-based access

Config-driven routing — zero code changes per client

The Problem

Complex enterprise expense workflows needed configurable, auditable approval chains that could be customised per-client without engineering changes.

What I Built

Built a fully configurable multi-level expense approval engine — from the database schema through the approval workflow UI. Supports N levels of approvers, conditional routing, and a complete audit trail for compliance.
