About Lionel Martis
I lead applied AI and engineering at Northern Trust, building AI systems across the full spectrum of enterprise applications—autonomous coding agents, research automation, document intelligence, domain-specific fine-tuning, and production machine learning—operating across a $14.2 trillion financial institution.As an early adopter of generative AI in financial services, I architect and deploy cutting-edge systems: agentic frameworks that write code and conduct research, fine-tuned models for financial domain tasks, model-agnostic platforms that work across commercial and open-source LLMs, and high-availability inference infrastructure that serves mission-critical applications.I build teams, set technical strategy, and create the capabilities that let a traditional financial institution adopt emerging AI technologies at speed. The work spans the complete stack—from distributed training systems and cloud infrastructure to evaluation frameworks and deployment pipelines—all designed to work within the security and compliance requirements of regulated banking.
