What brought you into Product Design?

I originally studied Computer Software Engineering, but I discovered I was more passionate about creating experiences than writing code. That led me to Graphic Design and eventually to Product Design, where I've spent the last 10+ years.

What's something people don't know about you?

I studied Creative Writing for two years and have published five books so far. Storytelling has had a huge influence on how I think about users, empathy, and product experiences.

If I asked your teammates about you, what would they say?

They'd probably say I'm the person who keeps everyone aligned. I enjoy bringing designers, developers, and stakeholders together to find solutions that work for users, the business, and the team.

What are you currently excited about?

The future of AI in Product Design. I'm continuously learning about Generative AI and exploring how it can enhance user experiences without losing the human perspective.
