Most hardware gets built around what the technology can do. I build around the people who depend on it.

The Challenge

Hardware fails earlier than most people realize, long before any prototype. Is the problem real? Has it been tested with users and decision-makers? Will anyone pay to solve it? Does the technology fit the people who will use it? When hardware is designed by people who only see half the picture, the prototype that gets made can't be manufactured, doesn't tell a story, or both. Once you realize it's wrong, you've spent the time and money you needed to make it right.

Hardware fails earlier than most people realize, long before any prototype. Is the problem real? Has it been tested with users and choosers? Will anyone pay to solve it? Does the technology fit the people who'd use it? Design gets made by people who only see half the picture, and the prototype that comes out can't be manufactured, doesn't tell a story, or both. Once you realize it's wrong, you've spent your time and money needed to make it right.

The Approach

Grounded in two decades of industrial design and product development, I design hardware that earns trust from the people who depend on it. A product changes hands many times, from design to engineering, then has to integrate across hardware, software, and service. The intent erodes a little at every pass. I stay hands-on through all of it, so what ships keeps the original intent intact. Driving decisions while changes are still possible, before tooling is cut.

Let's Work Together

01

Sprint

Sprint

A short, focused engagement with a clear deliverable. Workshops, design concept sprints, rapid research, or roadmap planning.

Best for teams with a specific problem and a deadline.

02

Partner

Partner

An embedded engagement from early concept to engineering-ready output. Industrial design, research, prototyping, and the strategic calls along the way.

Best for teams building toward a launch, fundraise, or pilot.

03

Advisor

Advisor

Director to VP-level design leadership, part-time. Run the ID function, set direction, and align hardware with software and service.

Best for teams that need senior design leadership, not a full-time hire.
