About

Engineer, builder, lifelong learner.

I'm Tô Gia Bảo, a Data Engineer at Timo Digital Bank by BVBank. I build cloud data pipelines, orchestration workflows, analytics systems and AI-assisted tools using Python, SQL, AWS, Airflow and dbt.

I care about explicit system boundaries, observable operations and designs that remain understandable as they grow. My current interests include lakehouse architecture, infrastructure as code and AI-native data tooling.
