How we turned an error list into a resolution guide

How I turned something the product team had watched for a long time and still couldn’t explain into a clear set of causes and a full quarter of product work.

- About me

Who am I?

A person driven by curiosity — about people, systems, business and why things work the way they do.

Good research isn't the hard part — making it matter is. Most of my work sits at the intersection of research and product decisions, where the goal isn't just to understand users but to actually do something about it.
