Hey, I'm Hong 👋

I build tools for things I care about: running, travel, and making everyday tasks easier. Based in Jersey City, currently training for the 2026 NYC Marathon.

Featured projects

Project What it does Explore
🎽 Bib Book Turn race bib photos into a private archive of running memories. Try it

⌚ Garmin Workout CLI Turn plain-English running workouts into scheduled Garmin Connect workouts. Source & setup

Watch the short demo

A workout in plain English 
10 min warmup, 6x800m at 5K pace with 2 min jog, 10 min cooldown

Garmin Workout CLI turns this into a workout draft you can review, upload, and schedule in Garmin Connect.
