Seoul, South Korea
Summary
👤
Senior🎓
Top SchoolRak Song is a full-stack engineer and founder based in Seoul with 12 years of experience specializing in frontend engineering using React, Redux, Vue.js and modern ES2015+ patterns. He has led redesigns of long-lived legacy systems—most recently re-architecting eBay Korea’s seller admin (Product Registration 2.0) using Vue—and built consumer-facing marketing platforms at Spoqa that span backend microservices, distributed tasks, and React frontends. Comfortable across infrastructure, DevOps and mobile runtime internals from his Samsung tenure, he blends low-level debugging experience (ART and kernel work) with product-minded UI architecture. As the founder of Pentarab he now focuses on building and monetizing innovative apps and web services while keeping hands-on with both code and system design. Colleagues describe him as a pioneer who seeks hard technical challenges and takes pride in clean, maintainable frameworks. He’s also quietly maintained hobby projects and tooling over the years, demonstrating curiosity across languages and systems beyond his day-to-day roles.
