About

More about me

Senior UX Designer and product design leader based in North Carolina. I’ve spent the last several years helping teams turn complex, data dense systems into tools people actually enjoy using. At Fidelity Investments, I have lead design efforts for institutional platforms and now serve as the Lead UX designer for the IWMS Design System, creating scalable components, maintaining documentation, and establishing best practices to ensure a consistent experience across products.

I care deeply about accessibility, thoughtful collaboration, and designing with purpose. Whether I’m mapping out workflows, mentoring teammates, or exploring how AI can enhance usability, I’m always looking for ways to make digital experiences more usable.

My experiences

I’ve had the opportunity to work across a range of industries, which has shaped the way I approach complex systems, workflows, and user experiences. I’m always drawn to challenges that push my design thinking and create opportunities to make products more scalable.
