I’m a freelance Data Scientist who helps teams turn messy, high-volume data into clear decisions and measurable growth. I’ve delivered end-to-end analytics and machine-learning solutions—data exploration, feature engineering, model development, and stakeholder-ready reporting—using Python (and R when needed). I’m comfortable partnering with cross-functional teams to define the right questions, translate business goals into data requirements, and present insights in a clear, concise way. What sets me apart is a practical, client-first approach: I focus on solutions that are reliable, explainable, and easy to deploy and iterate in fast-moving, remote environments.…I’m a freelance Data Scientist who helps teams turn messy, high-volume data into clear decisions and measurable growth.
