Rockstar🎓
Top SchoolYisheng Chai is a seasoned backend software engineer with 11 years of experience building high-performance, cloud-native systems and developer tooling across startups and platform companies. Currently at Kong working on AI gateway infrastructure, he has deep hands-on experience in Golang and Rust, contributed to notable open-source projects like casbin-rs (refactoring and dependency upgrades) and led Casbin work during GSoC. His background spans CDN and streaming optimizations, async runtimes and FFI for LLGo, Kubernetes infra, and observability, with measurable performance wins (e.g., 15%+ improvements and reduced crashes via lock-free mechanisms). Comfortable across systems, networking, and security, he also mentors OSS contributors and combines low-level systems thinking with pragmatic production engineering. An interesting detail: he pairs compiler/runtime work (IO_uring-based async FS) with cloud infra tasks, showing both deep systems chops and platform-scale execution.
