Product Designer focused on AI‑powered workflows and data‑heavy systems.

My focus areas

Design for complex products

I build dashboards, admin tools, and multi-step workflows that make essential rules, constraints, and edge cases understandable.

AI with a human in the loop

I create UX for non‑deterministic AI systems so people can guide their behavior, evaluate responses, refine or override results, and make informed decisions.

Design systems from the ground up

I maintain design systems that keep product structure, interaction patterns, and reusable components consistent as the product evolves.
