Independent work

Two ongoing projects: one explores how AI uses context; the other makes room for writing, editorial design, and thinking in public.

Personal knowledge platform · Research build

4ME OS

A self-hosted system for giving AI tools the right approved project context—without making any one assistant the source of truth.

Working core: Permission-scoped context previews and review-only change proposals, tested with synthetic data.
Still being tested: Whether reviewed context handoffs improve on simpler tools. Broad personal ingestion remains restricted.

Editorial application · Live publication

Newsroom

A personal publication about technology, changing careers, and everyday life. A newspaper on the surface; a deliberate editorial workflow underneath.

My work: Editorial design, application engineering, and a source-controlled publishing workflow.
In practice: Articles organized into desks, with explicit placement rules, review, and author approval before publication.

About

Language, judgment, and systems.

Before software, my work moved between classrooms, writing rooms, and legal offices. For more than fifteen years, I taught English and prepared students for the SAT, LSAT, graduate admissions, and application writing. I also wrote comedy professionally and worked in legal operations. Each required close reading, precise language, and judgment about what matters.

Those habits now inform product discovery, requirements, documentation, and the decisions that connect technical and nontechnical teams.

Based in Northern New Jersey. Korean and English. Away from work: hiking, guitar, reading, golf, and travel.
