A little about me
I’m interested in what happens when a lot of messy information becomes something useful. Not another dashboard full of numbers, but a product that helps someone understand what is happening, why it matters, and what to do next.
That interest grew through my work on a women’s health platform. I translated research into product requirements, helped shape symptom-tracking experiences, and structured information for an AI-powered health assistant. The challenge was not finding more information. It was making the right information clear, personal, and usable.
Now, that same thinking shapes projects like StrideSense, where I bring together data from different sources, define the logic behind the insights, and build around the questions a runner actually wants answered.
Alongside my own projects, I help small businesses turn early ideas and scattered content into clear digital products, from structure and visual direction through development and launch.
Whether it’s a role, a product idea, or a project that needs structure, I’d be happy to hear about it.
