Hey, I’m Dung (Yung), also known as Sunny, a Senior Data Engineer.
I build data platforms and pipelines. Over the past 7+ years, I’ve worked across different stacks like Snowflake, BigQuery, AWS, and GCP, building many things from scratch.
These days I’m particularly interested in agentic AI and how it can enhance data workflows.
Travel is one of my biggest passions. I’ve already visited many U.S. national parks, and I’m on a mission to see them all.
