Summary
👤
Senior🎓
Top SchoolBenjamin Cohen is a senior software engineer with 12 years of experience building robust front-end systems, developer tooling, and AI-assisted workflows from startup to enterprise. He has driven design-system rollouts and measurable product improvements (including a $12M/month revenue lift via A/B testing) while also owning marketing and consumer-facing surfaces with comprehensive automated testing and CI/CD. Benjamin pairs hands-on React/React Native expertise with backend API migrations (REST→GraphQL) and a track record of accelerating feedback loops—evident in automating assessments to cut grading from days to seconds. He’s taught and mentored hundreds of engineers at bootcamps, contributed to early AI tooling at Microsoft, and now reviews AI-generated code and crafts tests for a frontier AI lab, blending engineering rigor with curiosity about model behavior. Based in Salt Lake City, he brings a pragmatic, measurement-driven approach and a fondness for asking whether the machine will produce the right answers when fed imperfect inputs.
