For financial-services compliance, I built a regulatory knowledge graph that connects requirements across FINRA, the Federal Reserve Board, the OCC, the EU AI Act, DORA, NY DFS, the FDIC, and NAIC regulations into a single queryable structure.
The graph powers a continuous compliance monitoring system: instead of periodically sampling transactions for audit, every relevant event is checked against the applicable regulatory requirements as it happens, replacing sampling-based audits with continuous coverage.
