About Me

I'm an MBA graduate from Babson College (Business Analytics & Machine Learning, STEM designation) with a foundation in Econometrics and International Business from UC San Diego. I've spent the last 4+ years solving analytical problems from scoping through delivery — across operations, customer intelligence, and product strategy.

My toolkit covers the full analytics stack: from writing optimized SQL pipelines and Python churn models to building executive Power BI dashboards and deploying machine learning classification frameworks. I've worked across Fortune 500 supply chains (DHL), Big Four professional services (PwC), SaaS startups (GoSite), and enterprise tech (Staples).

I'm fluent in English, French (DALF C1), and Portuguese, which has allowed me to contribute to multilingual analytical projects across global client bases. I thrive in ambiguous problem spaces where first-principles thinking and data-driven rigor are required to define success metrics and build the infrastructure to measure them.

I'm actively seeking roles in Data Analytics, Data Science, and Strategy & Operations within the tech sector — particularly in health tech, consumer tech, and SaaS.
