What I'm looking for

I’m looking for a senior UX/product role where I can lead cross-functional, data-informed design—building cohesive experiences, strengthening design systems, and partnering closely with engineering to ship measurable improvements.

I’m a Principal User Experience Designer leading enterprise digital priorities at Fidelity Investments, where I partner across business units to unify fragmented internal systems and deliver cohesive, end-to-end client experiences. I drive cross-functional initiatives—defining and launching features with product and engineering, and upgrading legacy experiences—so users can confidently take action on their account security and profile needs.

Before Fidelity, I scaled design and research practices at MassMutual and led advisor-facing UX at State Street, including new design system efforts, a unified visualization library, and accessibility-focused work. Earlier, at Forrester Research and Pearson, I focused on data visualization and creating print and digital experiences for educational resources—strengthening my ability to turn research into clear, compelling interfaces for real users.
