Dear Hiring Manager, I am excited to apply for the Data Scientist role at {Company}. I build production machine learning models that drive bottom-line business impact: my last XGBoost churn-prediction pipeline reduced monthly customer churn by 18%, saving $1.8M annually.
I am proficient in Python, SQL, PySpark, TensorFlow, and Apache Airflow, and I focus heavily on deploying containerized models as low-latency microservices using Docker and FastAPI. I designed and evaluated 40+ A/B experiments that yielded a 14% conversion lift. {Company}'s work in {area} presents the exact high-leverage data challenges I am eager to tackle.
I would love to discuss your team's current data engineering and model prioritization goals. Thank you for your consideration. Sincerely, {Your Name}
