Hey! I'm Hyeseong, an integration engineer, open source hitchhiker.

I love OSS and enjoy going back and forth between different ecosystems and fusing the good things.

You can follow me as @cometkim on X, or @hyeseong.kim on Bluesky. Touch with DM anytime!

What I'm doing now

Studying compiler and storage technology. I'm working to make it my own skill by directly contributing to real-world compiler and storage projects.

Projects

  • ReScript: Modern compiler that compiles to JavaScript. I'm participating as a core maintainer, and improving its interoperability to JavaScript/TypeScript ecosystem.
  • ulottie: AOT compiler that compiles Lottie animations into a self-contained, lightweight JavaScript module.
  • dotunnel: BYOC(Bring your own Cloudflare) tunneling solution that focuses on developer experience.
  • Some secret projects...

Libraries

  • unicode-segmenter: The lightest and fastest Unicode text segmentation library in JavaScript.
  • rkyv-js: Rust rkyv implementation in pure JavaScript, for Rust-JS interop projects.

About Sponsorships
