How to use this cover letter
Dear Hiring Manager,

I'm excited to apply for the Data Scientist position. Data scientist reducing churn 11%, improving forecast accuracy 9 points, and accelerating experiment velocity 38% through production-grade ML pipelines.

At ModelCraft AI, I developed churn propensity models using gradient boosted trees and survival analysis, which effectively reduced customer churn and enhanced long-term value. I implemented a feature store and MLflow pipelines to streamline MLOps, accelerating model deployments and experiment cycles.

I have a track record of achieving -11% churn reduction, achieving +9 pts forecast accuracy improvement, and achieving +38% experiment velocity increase.

My key strengths include Ships production ML systems with measurable ROI, Implements governance to keep models fair, reliable, and explainable, and Leads experimentation culture that balances speed and rigor.

I'm known for strengths in machine learning, product impact, and experimentation while partnering with cross-functional teams.

I would welcome the opportunity to discuss how my experience can support your goals. Thank you for your time and consideration.
