Useful tools.
Built with people.

Vancouver · English + Korean

I help small business owners put AI to work. We start with a real problem, build something, and keep improving it.

01 / Hello

From “could we?”
to “try this.”

I’m a co-founder of Sundayable. I work with small business owners and teams on marketing, customer communication, and the tools behind the work.

I was a Lovable Ambassador from January to July 1, 2026, and I’m now an Alumni member. Co-hosting workshops taught me how much people learn when they build together.

With Codex, I want to run hands-on workshops and meetups in Vancouver, in English and Korean. People should leave with something they can use the next day.

Build together.
Learn together.

Workshops, shared screens, and plenty of questions. A few moments from my event archive.

03 / Built with Codex Astra

A useful first build.

Review Reply Studio helps small business owners write thoughtful replies to customer reviews in English or Korean.

Pick a tone, draft a reply, and make it yours. No account or API key needed. Review text stays in your browser.

Built and tested with Codex Astra. The app uses local templates; it does not call an AI API at runtime.

05 / What I’d bring

One real task.
One working tool.

My first Codex workshop would start with a small business owner’s daily task. We’d build a tool, test it, and put it online.

I’d share the starter repo, English and Korean walkthroughs, and a short recap. Then bring feedback from the room back to the community.
