Proven ability to drive epic-level frontend work end-to-end

Strong testing discipline: unit, integration, and end-to-end coverage

Collaborative approach to working with Design and Product on future projects

Strong opinions loosely held

What Sets You Apart

Experience building or contributing to a shared component library or design system

Familiarity with backend APIs — you can read service contracts, have an informed conversation with backend engineers, and understand what's feasible
