Why over how
I'd rather understand the cause than ship the fix. Both belong in the final answer — the order matters.
About
One identity isn't quite enough.
Korean lead software engineer based in Bangkok since 2016. I've been writing software since 2005 — long enough to have lived through Visual Studio 6.0, the web's reinvention, the rise of mobile, cloud, and now AI inside the loop. I lead engineering teams, ship product, and care about the part most people skip: the boring middle where good systems are actually built.
Started running seriously in 2023. Three years later: 10K 40:10, half marathon 1:35, full marathon 3:28:08 at Hua Hin. Sub-three is the next thing the road is asking me about. Outside the desk and the road, I move through cities slowly — nineteen so far, with Bangkok as the steady center. Engineering, running, travel: three faces of one habit — show up, pay attention, do it again tomorrow.
Timeline
Three starts.
- Engineering
2005
First commit. Visual Studio 6.0, dial-up era.
- Bangkok
2016
Korea → Thailand. Still here.
- Running
2023
Started for real. The numbers followed.

What I care about
AI changes the work, not just the speed
Faster output is the easy part. The harder part — and the one I'm spending years on — is rebuilding how engineering teams actually think.
Show up tomorrow
The runner who keeps going outlasts the one who ran fast once. Engineering is the same. So is travel. So is writing.
