04 / HOW I WORK

Follow the problem.
Check the result.

A practical process shaped by prototype labs, product teams and time spent finding out why a device behaves the way it does.

01 / UNDERSTAND
Start at the system.
Understand the use case, interfaces and physical constraints before choosing a solution.
02 / BUILD
Connect the layers.
Bring electronics, firmware, mechanics and application behaviour into the same conversation.
03 / VERIFY
Make it observable.
Use measurements, device feedback and repeatable checks to test assumptions.
04 / REFINE
Close the loop.
Follow issues through implementation, document what changed and verify the target again.
