Senior🎓
Top SchoolChangyeop Kim is a pragmatic technology leader and CTO based in Seoul with 13 years of hands-on experience building high-performance trading systems and consumer-facing applications. At HEYBIT he architected a Rust-based quantitative trading platform capable of executing tens of thousands of orders per second and built the supporting JS API, Kubernetes operations, and big data pipelines on AWS. His background spans mobile and backend systems from Android/XMPP clients and realtime chat servers to Node.js and Vue.js web apps, reflecting deep full-stack fluency. He doubled market-data collection performance by selectively introducing Rust into Python systems, showing a pragmatic mix of language-level optimization and engineering tradeoffs. Educated in computer science and management science at KAIST with an exchange at RPI, he combines technical depth with product and operational sensibility. He’s equally comfortable negotiating with global crypto partners as he is diving into low-latency systems and data infrastructure.
