I'm Jia He.

I spent 10 years managing millions in paid media. Now, I'm building the systems to automate the parts that suck.

I didn't set out to be technical. I started writing scripts because I wanted an unfair edge in performance marketing. Today, I build the AI-powered workflows, agentic systems, and data infrastructure I wished I had when I was running campaigns across 15 countries.

What you'll find here:

• No AI hype — Just whatever that works to solve real problems be it Python, SQL, or AI.
• The Work — Documentation of the tools I'm building for myself and marketers.
• The Edge — How to start building your own tooling.
