Donald Jordy
Data Scientist
I'm a data scientist focused on rigorous analysis, practical machine learning, and clear communication — from raw data to findings a team can actually act on.
currently: Building out my project portfolio — an end-to-end churn prediction model and an exploratory analysis of a public dataset — while studying [PLACEHOLDER: current coursework or certification].
