Hey,

I’m Dongsun Moon.

I build software and write about it. I currently work on AI agents at Dialpad. In the past, I worked on ordering systems at Amazon.com and on Need for Speed at Electronic Arts.

I published Beyond Microservices and am now working on follow-up books. I enjoy writing about AI, backend systems, distributed systems, and the engineering ideas I find interesting along the way.

This blog is a place for those notes, ideas, and experiments.
