Top SchoolHyeonsu Lee is a product-minded software leader and serial founder with 11 years of experience building customer-facing web and mobile services from Seoul.

Previously he led major React and React Native rewrites at Toss Global and built frontend infrastructure and CI/CD practices that improved developer velocity across teams.

Trained in business administration, he blends product intuition with technical depth and a pragmatic bias toward shipping. A detail not obvious from titles: much of his impact has come from improving developer tooling and processes that scale teams as well as code.
