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. As Co-Founder & CEO of IF Corp. and Else, Inc., he pairs hands-on frontend engineering expertise with startup strategy and operational leadership. 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. His background spans rewrites of legacy stacks, web-based insurance and payments features, and embedding developer cultureโskills that help turn messy product ideas into reliable, shippable experiences. 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.
