Work

This is a selection of product and client work I helped shape over the years. Today I bring that experience into the AI era: designing interfaces, workflows, and agent-powered systems with a strong technical understanding of established web stacks and modern AI-native product development.

You can also find me contributing to open source and challenging new ideas with design, code, and data. I work best where interaction design, engineering, and AI systems meet.
