What I'm looking for

I seek roles where I can build production ML solutions, collaborate cross-functionally in Agile teams, and drive measurable retention, growth, and ROI.

I am a results-driven Senior Data Scientist with 15+ years building production-ready machine learning and predictive analytics solutions across gaming, finance, and manufacturing. I deliver models and data products—retention, fraud, personalization, and segmentation—that measurably reduce churn, prevent loss, and increase revenue.

I combine deep technical skills (Python, R, SQL, Spark, TensorFlow, XGBoost) with cloud and tooling experience (Azure, OCI, Snowflake, Databricks, Dataiku) and Agile leadership to partner cross-functionally and translate analytics into business impact. Highlights include retention lifts up to 15%, downtime reduction of 20%, and improved product penetration and member growth through targeted ML-driven strategies.
