About Me

I’m currently working as a Research Scientist for The Vera C. Rubin Observatory - Chile. I have an MS in Data Science from The University of Washington - Seattle. I've worked as a Data & Machine Learning Engineer for Shell where I developed and deployed some of the most sophisticated and successful data-powered products to help traders generate $500+ Million/year in revenue. I've hands-on experience in taking products from ideation to production in both, startup and corporate environments. I possess a strong foundation in data science, machine learning, data engineering, and operations. Let's connect and discuss how we can work together to build something awesome!
