Hello, I'm Duan Nguyen Duy 👋

About Me

I'm a data engineer with hands-on experience in building and maintaining data pipelines, specializing in Apache Airflow orchestration and Salesforce Marketing Cloud integrations. My background includes working with Customer Data Platform (CDP) solutions, particularly Antsomi CDP 365. I'm passionate about exploring data, understanding the issues surrounding it, and leveraging data to derive actionable insights. With practical knowledge in data integration, ETL development, system monitoring, segmentation, and analytics reporting, I help organizations build robust and scalable data infrastructure while unlocking the power of their customer data.

My experience has strengthened my technical skills in data engineering tools, workflow automation, and BI tools while developing my business acumen. I excel at understanding requirements and delivering data solutions that address real business challenges.

Coding is also something I quite enjoy - there's a lot of logic shown when programming something interesting.
