ResumeSay Hello

Who I Am

Engineer with a product mindset.

I build at the intersection of frontend craft and product thinking. At HubSpot, I lead large-scale frontend migrations across 5+ repos, architect performance-critical features, and leverage AI tooling daily to accelerate delivery across massive codebases.

B.S. Computer Science & Mathematics from the University of Florida, graduated Cum Laude. I take initiative, obsess over details, and always develop with the end user in mind.
