I excel at partnering with cross-functional teams to unify product, marketing, and CRM data, enabling real-time strategy pivots and enhancing decision-making processes.

Throughout my career, I have conducted user behavior analysis and market research to inform MVP development and roadmap prioritization. My expertise in Python, SQL, and modern BI tools like Power BI and Tableau has allowed me to develop AI-driven segmentation tools that enhance personalization and operational efficiency. I am passionate about delivering insight-led product improvements and aligning stakeholders to drive data-informed decisions.
