Experience

1. Principal Data Scientist

   DEPT®

   Jan 2024 — Present

   I lead a team of data scientists and analysts to help clients shape business and data strategy—translating ambiguous medical and industrial challenges into production ML solutions. I own the full engagement lifecycle (scoping, pricing, architecture, delivery, adoption) and apply depth in data mining, predictive modeling, forecasting, deep learning, and MLOps to build, monitor, and continuously refine models that drive measurable business outcomes while managing stakeholder expectations and alignment.Key focus areas- End-to-end leadership: scope → pitch → plan → build → deploy → retrain with clear ROI and risk tradeoffs- Technical stewardship: model lifecycle infrastructure (pipelines, monitoring, drift detection, retraining governance)- Team + client orchestration: turning complex asks into structured problem frames and scalable solution patterns- Impact orientation: anchoring every model to margin, efficiency, risk reduction, or strategic differentiation
