I Build
Systems, Not Apps
I design vehicle systems by day. Nights and weekends, I architect complete digital systems — from AI learning platforms to multi-agent frameworks — then ship them for everyone.

RunDNA
Runners don't just need data — they need to understand their running identity. I built an AI system that decodes it from Strava.
AI-powered running analytics platform. Connect Strava, discover your 5-axis runner personality, chat with an AI coach, generate race plans, and share weekly reports. Bilingual (EN/KO).
Prompt Garden
The client needed prompt engineering to feel like design, not guesswork. So I built a visual IDE for it.
Visual prompt engineering workspace. Build, connect, and test AI prompts with a node-based editor. Shipped with custom domain.
EngReading
v5.0 — Korean sentence in, English brain out. AI classifies your verb into 1 of 7 Sets and animates how a native speaker builds the sentence left-to-right.
Forward-Flow English Brain Rewiring Engine. Input any Korean sentence, AI classifies the core verb into 7 Sets and animates the native English thought process. Gamified with XP, streaks, radar mastery charts, and SM-2 spaced repetition review.
Currently Building
Active client projects in development. Working demos available.
Running Club Analytics
Building the club version — individual engine is live with 170+ runs of real data. Partner needed for scale.
Strava-connected club analytics platform — member rankings, group pace optimization, injury prevention monitoring, and GPS-based meetup recommendations. Proof of concept running with real data.
Enterprise Decision Agent Team
Building for a client — AI departments that debate enterprise decisions so humans don't have to go in circles.
Multi-agent decision simulation where AI agents with conflicting KPIs debate enterprise decisions through structured analysis, cross-critique, and consensus. Live demo with automotive industry scenario.
Claude Writer
What if your note-taking app could think? I built an AI writing assistant that lives inside Obsidian's sidebar.
Obsidian plugin that transforms your notes with Claude AI — rewrite, restructure, translate, explain at 4 depth levels, and auto-generate Mermaid visualizations. All powered by Claude Code CLI.

Off the Clock
Software is where I build. Reading and running are where I think.
Need a System, Not Just an App?
I design systems that solve real problems — from AI architectures and multi-agent frameworks to data pipelines and browser extensions.
Whether you need a working prototype, a production system, or a proof of concept to pitch investors.
