Gyumin Choi (catuscio)

I’m an AI software engineer and backend developer. At Kimcaddie, I joined as an AI engineer and also work on backend development.

• Developed Kimcaddie AI Swing Coach, a real-time multimodal golf coaching agent that gives voice-to-voice feedback on swing form.
• Built Querycaddie, a SQL-powered Slack bot tailored to internal company data so anyone can ask questions in natural language and get AI insights.
• Built Kimcaddie Class, an open marketplace where golf professionals offer one-day group lessons.
• Reworked the internal admin around business policies, significantly reducing the time and complexity of operations.

For side projects, I build services as I need them (and invest over $300 a month in AI subscriptions).

• notion-as-blog: an SEO-optimized blog template powered by Notion CMS
• 누렸음청년: a service for finding and recommending youth support programs and policies
• The official website for indie band Hoerang
• And more

I value end-to-end ownership: looking beyond code to anticipate the problems a product may face in operation, working through them with the team, and shaping the right policies.

I’m drawn to visions worth pouring time and passion into, and to teams united to make them real.
