I'm a Product Designer with over 15 years of experience making complex products easier to use. Much of my work revolves around AI, from agentic systems to automation and human-in-the-loop workflows.


At Hive, I design automation for a global event marketing platform. I use Claude Code and native MCP to build reusable, production-ready design-system components. I stay hands-on from design to code.

Before that, I led AI experiences within Microsoft. I've also worked on machine learning and automation at Qlik, on government platforms, and with startups through Toptal. Earlier in my career, I ran my own design practice and worked at brand agencies, where I learned to defend design decisions directly to the people paying for them.

Outside work, you'll find me mentoring, writing, practicing aquascaping, building AI side projects, and always learning something new.

Design Approach

I start in the messy part, asking questions to figure out what’s actually worth solving. From there, I explore different directions, prototype ideas, then make the case for what works best. With AI in the mix, I consider technical constraints, user needs, and business goals from day one.
