안녕하세요 — I build products with Ruby on Rails, with a soft spot for small teams, long-term maintainable systems, and shipping things that last.
These days I'm based in Toronto. Outside of work I keep a homelab humming, self-host the tools I rely on, and poke at where AI coding tools are headed.

Writing
On this blog I write about Rails server development, self-hosting & homelab, and the shifting landscape of AI coding tools — and I run a Korean Ruby on Rails newsletter.
