About Kai

A product builder.
A healthcare perspective.

I care about building products that make healthcare feel more human.

Following the work.

My career has moved from healthcare operations and claims data into digital health, patient–clinician matching, and AI-enabled products. Across those settings, the work has meant understanding what people need, where a workflow breaks down, and what a product can meaningfully change.

At Optum, I founded Optum Match and worked on virtual care and digital acquisition. Today, I’m a Principal Product Manager at Syneos Health. My experience there includes early strategy and prototyping for pharmaceutical patient-support orchestration.

I work across product, engineering, data, design, clinical, and business teams. I’m especially interested in the decisions that shape a new product: which problem to start with, what to build first, and how to know whether it helps.

Making room to explore.

Hands-on prototyping is part of how I work through product questions. My personal projects explore AI assistance, exception handling, and the boundaries between automated work and human judgment.

I also enjoy cooking and exploring new cuisines. What I Made grew from that interest: a small cooking journal for remembering dishes, revisiting past attempts, and seeing where that curiosity takes me.

I enjoy hiking, diving, and landscape photography. I also love spending time with my family. We’re frequent visitors to the Discovery Children’s Museum.
