Top SchoolSimmon Li is a Senior Software Engineer with eight years of startup-focused experience building full-stack Rails applications and shipping production features across Ruby on Rails, PostgreSQL, React, Hotwire and ViewComponents.

Comfortable spanning backend, frontend and infra, he’s delivered complex workflows like Turbo/Stimulus image uploads and redesigned checkout and onboarding flows to boost conversions. A Toronto Ruby organizer and active Rubyist, he pairs grit from earlier operations and finance roles with disciplined engineering practices like Sorbet typing and comprehensive RSpec suites.
