Manager, International Trade

Data Scientist | Consultant | Lean Six Sigma MBB

From Lean Six Sigma projects to data science solutions, I've turned complex business problems into strategic opportunities. My key to success? Bridging the gap between business and technology. With expertise in project leadership, data science, and business strategy, I help companies unlock their potential using data-driven decision-making.

My journey has led me through the corridors of Fortune 50 giants like Cargill and HP, where I led various teams, and implemented tech solutions for business success. Then I left the big corporate world and I witnessed first-hand the challenges of the small-medium sized businesses. My work in time series forecasting, customer segmentation, and attrition prediction has informed strategic direction and uncovered untapped opportunities.

Today, as a consultant, I'm passionate about extending this impact beyond corporate boundaries. I leverage my diverse skill set to help businesses transform their operations, enhance productivity, and drive growth through the power of data and AI.

If you're ready to leverage data science and AI for your business, I'm here to catalyze that journey. Let's partner to navigate the data-driven future together.
