A bit about me

I am a senior product designer based in San Diego, California. I’m currently an Interaction Designer at HP, focusing on the ink subscription experience during printer setup.

Before transitioning into UX, I worked as a wedding photographer, graphic/web designer, and architectural drafter.

In my free time, I enjoy journaling, listening to podcasts, watching my fish in the aquarium, or playing pickleball with friends.
