Structure the complexity
Translate technical rules, operational exceptions, and user goals into a product flow the team can reason about.
I stay with a product until the interface works in the real world.
I do not treat a product problem as a screen problem. In data-labelling tools and cloud-printing services, I have worked through the operational rules behind the interface: file conversion, payment, printer communication, task state, and field installation.
My strength is turning those constraints into flows and standards that planners, engineers, and operators can use. I define edge cases early, follow implementation closely, and check the product in the environment where it will run.
More recently, I have designed and built independent products through App Store review and web deployment. That experience keeps my design decisions grounded in code, release constraints, and ongoing maintenance.
What I bring
Connect every surface
Keep the experience coherent across mobile, web, PC, kiosk, multifunction printer, and the physical environment around them.
Follow through to release
Work across Figma, prototypes, documentation, design QA, implementation, deployment, and field validation.
