He currently leads product and technology work for Gaia at UBITECH.

## Speaking topics

- **From AI experiments to operational products:** What changes when AI moves beyond pilots into owned workflows, measurable outcomes, operating controls, and continuous improvement.
- **Agentic AI platforms and control planes:** How tools, models, context, permissions, evaluation, and observability come together when agents become long-lived systems.
- **Governance as a product discipline:** Why trustworthy AI depends on practical product and engineering choices rather than policy documents alone.
- **Product leadership across technology waves:** Lessons from visual computing, medical software, developer platforms, and AI about what changes—and what remains durable—in product work.
