About / Yung Ju (Rick) Kim

Engineer, with a
product perspective.

A little context

I am a Lead Software Engineer at Business Canvas in Seoul. I build products where AI agents meet real workflows, permissions, and production constraints.

I started in frontend product engineering and gradually expanded across mobile, backend contracts, developer tooling, and team systems. I care about turning individual productivity into ways of working that a team can understand, repeat, and improve.

Outside product work, I explore how AI should participate in engineering decisions. Gochal, my open-source Claude Code plugin, helps people examine trade-offs before accepting a recommendation.

Working principles

  1. Start with the real workflow

    Design from concrete user and failure scenarios, not abstract feature labels.

  2. Make boundaries explicit

    Permissions, ownership, privacy, and failure modes are part of the product design.

  3. Turn individual speed into team leverage

    Document decisions and build systems that teammates can understand, repeat, and improve.
