Studio
Fast execution, product sense
Not "more features" — a flow people keep using. A one-person studio that builds AI apps, ships them on Google Play and runs them.
Principles
Build fast → improve from how people respond → settle it into something that can be run.
Strengths
When AI goes into a product, one person weighs the UX, cost, performance and operations together.
Working together
Short cycles of sharing and feedback → fast iteration. Docs, schedule and priorities stay in the open.

Seunghyuk Park — a one-person studio
LightOn Plus Lab is a studio run by Seunghyuk Park alone. Planning, design, development, release and operation all sit with one person, so decisions are quick and no context gets lost.
