About Me

Highly effective working from home office across time zones.

I’m a product and systems leader focused on designing complex, human-centered platforms—most of my work has been in educational assessment, where usability, data, and measurement all intersect.

My background began in engineering and applied physics, developing solutions and electro-mechanical products across high-tech and industrial sectors. That experience continues to shape how I approach problems: as interconnected systems that need to function reliably under real-world conditions.

More recently, I spent over 10 years at ETS where I worked at the center of the transition to digital assessment for NAEP science and mathematics programs, helping shape how interactive tasks, student behavior, and system design come together to produce meaningful, scorable evidence. My work has spanned product strategy, assessment design, UX and accessibility, and the operational systems needed to deliver large-scale programs.

What draws me to this work is the challenge of making complex systems actually function in practice. In assessment, that means more than just building features—it means ensuring that what students do can be interpreted reliably, fairly, and at scale.

More broadly, I’m interested in how systems translate human activity into data, and how that data can be used to support learning, decision-making, and more nuanced forms of measurement. That interest has led me into ongoing research in science learning and assessment, as well as exploration of how AI and structured data systems might support more complex, performance-based evaluation.

How I Work

I tend to operate at the intersection of disciplines—bridging product, engineering, and domain experts to move complex work forward. A lot of my value comes from translating between perspectives, clarifying ambiguity, and structuring problems so they can be solved effectively.

I’m particularly drawn to environments where:

  • systems are complex and evolving
  • multiple stakeholders need to align
  • the quality of the solution depends on getting the details right

Beyond Work

Outside of my professional work, I tend to gravitate toward hands-on, system-oriented projects.

I’m currently working on an electric vehicle conversion of a classic Land Cruiser, which has been an ongoing exercise in integrating mechanical, electrical, and control systems into a cohesive whole.

I also spend time playing and learning music—guitar and mandolin, and more recently bass—which, in a different way, involves pattern recognition, structure, and incremental refinement over time.

I value time with my family and exploring the Pacific Northwest, which provides a welcome contrast to more structured, technical work.

Looking Forward

I’m interested in roles where I can continue working at the intersection of product, systems, and measurement—particularly in environments that value thoughtful design, collaboration, and tackling complex problems that don’t have obvious solutions.
