About

A bit of a product all-rounder

I help founders and product teams turn product strategy into faster delivery, less rework, and better business outcomes.

I work across the full arc — discovery, product design, and delivery — so decisions hold up from the first prototype to the shipped product.

Before focusing on product work, I worked with founders on their businesses, marketing and growth strategies. I also led a performance design team at an agency and have mentored product designers.

I increasingly bring AI into the process to move faster without cutting corners. For larger or more technically complex projects, I also collaborate with engineering partners.
