Rockstar🎓
Top SchoolChulki Lee is a founding software engineer and seasoned technology leader with 13 years of experience building scalable back-end systems, developer tooling, and cloud infrastructure in the San Francisco Bay Area. He has led teams of 15+ engineers and owned technical roadmaps across product, security, and operations—driving migrations (Zoom to Amazon Chime), GDPR compliance, and company-wide on-call and observability practices. Hands-on across Ruby, Elixir, and cloud tooling, he has contributed to notable open-source projects like Puma, Phoenix, and Tesla, improving server architecture, HTTP client correctness, and build/deploy workflows. Equally comfortable architecting systems and shipping code, he brings a pragmatic balance of technical depth, automation focus (build/release and CI updates), and remote collaboration fluency. A continuous learner with advanced degrees from Seoul National University and UC Berkeley, he combines research-minded rigor with startup grit and a knack for turning operational complexity into reliable platforms.
