About
A bit about my journey so far
Frontend Developer with 4+ years of experience turning designs into interactive, accessible web experiences, both independently and as part of a team.
I care about the small details that make an interface feel right, communicate clearly with designers and engineers, and enjoy picking up new tools as projects call for them.
Open to new opportunities. Let's connect.
