Hi! I'm Jaeha ๐Ÿ‡ฐ๐Ÿ‡ท, a software engineer. TypeScript by day, Rust ๐Ÿฆ€ by night.

I like building software that's small, fast, and a little fun โ€” abstractions that earn their keep, UIs that don't lag, code I can hold in my head.

If you want to talk about TypeScript, Rust, or anything in between, let's chat.

Currently

Shipping side quests things in TypeScript by day โ€” front-end and a bit of full-stack wherever it's needed.

At night, going deeper into Rust ๐Ÿฆ€ โ€” ownership, async, and whatever rabbit hole the day's code left open.

Always poking at side projects and writing about what I learn on this blog.
