Client / Problem Overview
- Industry: Financial Services & Global Banking
- Scale: 85,000+ Employees globally
- Business Challenge: The client deployed numerous isolated LLM applications without centralized oversight, leading to exponential API cost overruns and fragmented operational silos.
Leadership & Execution Focus
As the Technical Project Manager and Solution Architect for this global engagement, I actively led the transformation from end-to-end. I successfully managed, delivered, and architected the highest level of business strategy while simultaneously diving deep into the technical execution required to centralize the bank's AI portfolio.
Challenges & The Cost of Doing Nothing
The organization was facing three distinct threats to their AI roadmap. Leaving these unchecked was not just an operational flaw—it was a critical financial liability.
- Runaway Compute Costs: Unoptimized API calls and lack of caching mechanisms led to a $2.5M monthly Azure OpenAI run rate.
- Shadow AI Implementations: Business units were deploying unsanctioned models utilizing sensitive internal data, bypassing Infosec protocols.
- Compliance Liabilities: Without centralized logging, auditing AI inferences for HIPAA, SOC2, and internal risk management was impossible.
"Generative AI without a strict central governance gateway isn't innovation—it's just scalable shadow IT."
Solution Approach
To halt the cost hemorrhage while scaling capability, we implemented an Enterprise AI Gateway & Governance Platform. Rather than departments accessing external LLM APIs directly, all traffic was routed through a centralized proxy layer. This allowed us to introduce systemic monitoring, caching, and role-based access control (RBAC).

Architecture
The foundation of the turnaround was the new centralized architecture. All department-level AI queries were routed through the Zenith Gateway, enabling real-time auditing and semantic caching.
