Dear hiring team,
I understand that the central requirement for this Data Scientist role is framing analytical questions, preparing trustworthy data, selecting methods, validating models, and explaining decision limits. I am drawn to data science that improves decisions by making uncertainty explicit, not by hiding it behind model complexity.
I completed this work during a supervised Data Scientist Intern placement. Under supervision, I separated training and evaluation data by time and customer, inspected leakage in derived features, and compared model performance across cohorts before recommending an experiment.
Within that same supervised placement, I limit my claim to the assigned work. Under supervision, I built a Python machine learning baseline for repeat-purchase prediction, split observations by customer and time, and compared calibration and recall with a simple statistical baseline before presenting the model recommendation.
I would welcome the opportunity to discuss the decisions and delivery I owned, and how I could apply that experience in this role.
Sincerely,
J. Lee
