What I'm looking for

I seek an analytical role where I deliver pricing/cost insights, build scalable data pipelines, automate workflows, and work within a collaborative, growth-oriented team.

I am a data analyst with experience driving cost- and pricing-focused insights in fast-paced e-commerce environments. I combine practical skills in Python, Google BigQuery, and visualization to automate workflows and deliver actionable dashboards that improve decision-making.

At Wayfair, I served as Senior Business Analyst for EU Pricing, leading ship-cost and customer-service cost-model improvements that increased cost accuracy and supported strategic initiatives. Previously, I optimized data operations and automated repetitive processes, saving substantial operational time and enabling scalable analytics.

I hold a Data Science bootcamp certificate from Le Wagon and a bachelor’s in International Business Management, and I continuously expand my technical toolkit while enjoying functional training, nutrition, and photography outside of work.
