Senior🎓
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. Based in Toronto, he blends hands-on engineering with product-minded execution—rewriting search into a microservice, re-architecting AI generation, and raising test coverage to ~92% to materially reduce errors and improve retention. 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. Notably, his background in project management and jazz performance hints at a mix of structured process and creative collaboration in product delivery.
