Elle Pereira

Senior Software Engineer II

Portland, OR

I'm a staff-level frontend engineer with 18+ years building high-traffic products — leading StyleSeat's migration off AngularJS to React, architecting its design system, and mentoring engineers along the way. Outside of work, I lead a team of 30 reverse engineering a defunct MMO back from the dead.
