Proving the controls-by-design pattern travels beyond one bank — by shipping it as code.

The brief

The governance pattern that secured CCO sign-off at Deutsche Bank — explainability, a full audit chain, human-in-the-loop review, confidence gating before anything reaches a regulator-facing decision — isn't a one-bank trick. Between roles, I set out to prove it: not as a slide, as working code. Six agents, one shared controls library, all live on GitHub.

The architecture

The interesting design decision wasn't any single agent — it was refusing to let five different repos reinvent the same safety controls five different ways. Every agent that makes a decision a human would otherwise have to catch imports the same shared layer.

One controls library, five agents importing it. Fix a gap once — every agent above inherits the fix.

Why this, not another slide deck

Measured impact
6 Production-grade AI agents shipped and live on GitHub.
1 Shared controls library imported by every agent above.
20+ SQL dialects supported by the lineage-parsing agent, with no database connection required.
0 Agents that auto-approve a high-risk decision without a human gate.

A hiring manager can read a bullet point about "responsible AI" on any resume. This is the difference between the claim and the artifact: the code is public, the guardrails are documented in each repo's README, and the pattern is the same one that got sign-off from a tier-one bank's Chief Compliance Officer.
