Creighton Hejduk

I'm a product designer with 5+ years of experience who believes great design doesn't stop at the handoff. I care about pixel-perfect work and about making sure what gets built actually matches what was designed.

Most of my recent work has been on the infrastructure side of AI design tooling — building the harness rather than the output. Deciding what a model is allowed to know, what it has to ask for before it writes anything, and what it gets refused for turns out to be interface design; the user just happens to be a machine.

I'd rather measure that than assume it. The systems I build come with the experiments that show whether they work, including the rounds where they didn't.
