Principal AI Architect | Forward Deployed Engineer | Agentic AI for Regulated Finance | Engineering Leader

About

Nabendu architects frontier AI systems for the world’s most regulated industry — with 22 years spent earning the right to be trusted with that. His work lives at a specific intersection: where agentic AI meets banking regulation, where prototypes must survive auditors, and where a CxO’s ambition has to become an architecture that actually ships. He sits between the boardroom and the engineering squad — shaping pursuits, building what he proposes, and staying accountable for whether it delivers. The foundation is two decades inside the machinery of global finance — Visa, Standard Chartered, Oracle, DBS, Credit Suisse, Barclays, and EY — across Singapore, the UK, and India. Payments, fraud, digital banking, cloud and security transformation. He has seen what breaks in regulated environments, which is precisely why he knows how to build what doesn’t. Today that experience is pointed at the frontier: agentic AI architecture, AI governance, and post-quantum security for financial institutions across Australia, the UK, and the US. OpenAI-certified, NVIDIA GSI Hackathon nominee, patent-holding — but the credential that matters most is simpler: clients trust him with systems where failure isn’t an option. He writes and speaks on agentic AI governance and the architecture of trust in financial systems. Open to hard problems at the intersection of AI, risk, and regulated finance.
