Hyun Woo, Choi

Product-focused Builder

I am a developer and analytics graduate student who works at the intersection of data science and systems engineering. My work focuses on building data-driven systems — from collecting and structuring data, to developing predictive models, and implementing the systems that make those models usable in practice. With experience in enterprise software development and financial ERP systems, I approach data problems with a systems perspective: understanding how data flows through real-world systems and how analytical models can be integrated into them. I am particularly interested in reproducible research, machine learning model improvement, and building practical systems that turn data into reliable decision-making tools.
