About An Nguyen
Backend engineer · Ho Chi Minh City
I am a backend engineer based in Ho Chi Minh City. Over the past seven years I have worked on .NET services, PostgreSQL-backed SaaS products, and data pipelines on Databricks.
Lately most of my day goes into AI-assisted engineering workflows — figuring out where coding agents genuinely save time, where they quietly add coordination cost, and how to test the difference.
This blog is a working notebook. I write when a debugging session, a post-mortem, or an experiment leaves behind something worth keeping.
