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.

  1. 01 / UNDERSTAND

    Start at the system.

    Understand the use case, interfaces and physical constraints before choosing a solution.

  2. 02 / BUILD

    Connect the layers.

    Bring electronics, firmware, mechanics and application behaviour into the same conversation.

  3. 03 / VERIFY

    Make it observable.

    Use measurements, device feedback and repeatable checks to test assumptions.

  4. 04 / REFINE

    Close the loop.

    Follow issues through implementation, document what changed and verify the target again.
