Senior🎓
Top SchoolSubeom Choi is a Lead SDK Software Engineer based in Seoul with a decade of experience building reliable, testable SDKs and seamless deeplink flows that move users between web and apps. At AB180 he designed modular, reactive iOS and deeplink architectures, unified SDK interfaces across platforms, and cut system costs by roughly $160,000 per year through pragmatic optimizations. He balances low-level performance work (including Rust contributions to notable projects like redis-rs and xi-editor) with high-level API design to produce readable, extensible, and robust code. His background spans mobile, web, and cross-platform SDKs (React Native, Flutter, Cordova, Expo, Unity), and he champions specification-first development and better team practices. Known for improving testability and developer experience, he also contributes to open-source Rust libraries that touch core protocols and editor behavior.
