Looking back at how I find and solve problems.

I write about problems that involve technology, systems, and teams. I look at the real problem, the limits I faced, the choices I had, and what I did next.

This is not only a list of success stories. I also write about unexpected results and what I would change next time.

Each post starts with rough notes from my workday. AI makes Korean and English drafts at 1 p.m. Korea Standard Time. I check the details and approve each post before it goes live.

Before a post goes live, I remove private work details. I do not share company or customer names, internal addresses, security details, contracts, or personal information.

My profile and personal projects are on my profile and projects page.
