02 Selected work

Six systems.
One way of working.

Each project starts with a complicated workflow and ends with a tool that makes the next step clearer.

03 Capabilities

Across the whole system.

Useful products rarely stop at one discipline. I move between strategy, interfaces, code, workflows, and the physical prototype.

04 System profile

Curious enough to cross disciplines. Practical enough to finish.

My work sits where digital tools meet materials, machines, and people. I learn by building, reduce complexity through iteration, and care about the last mile between a technical possibility and a usable product.

01Understand the real workflow before choosing the technology.

02Make progress inspectable through prototypes, tests, and visible decisions.

03Connect disciplines instead of optimizing one layer in isolation.
