Hi, I'm Jin Yoo.

I've built software and taught how to code in the past. Most recently, I was an AI Engineer at Block building internal AI tools for improving developer velocity before being impacted by the large layoffs.

I write about programming, AI, and anything else that interests me.

I've been thinking about this a lot recently and agree with all of the author's points; what the author describes has become how I develop.
