Hey! I'm Hyeseong, or @cometkim, an integration engineer, open source hitchhiker, and DX enthusiast.

I love OSS and enjoy going back and forth between different ecosystems and fusing the good things. I'm currently focusing on improving the experience of ReScript, TypeScript, and GraphQL projects.

You can follow me (@KrComet) on Twitter, and touch with DM anytime!

What I'm doing now

Building "espub" which is potentially a best-in-class library build tool for JavaScript/TypeScript ecosystem. (See https://github.com/cometkim/nanobundle/issues/231) So it will make you never get frustrated again when creating your own library. for Node.js, Bun, browsers.

Discovering RAG(Retrieval-Augmented Generation), I'm interested in ways to increase infra-level productivity when building something small products for myself.

I've started to contribute directly to the ReScript compiler. I've been contributing to the ReScript community, but I eventually realized there's a lot more I can do at the core. I will be championing various features in v12 that will maximize the interoperability of ReScript and JS/TS projects. For example, the "Library Mode"

I also build and maintain some third-party integrations to connect each others
