I am a data-driven analyst with over five years of experience designing experiments, analyzing user behavior, and delivering actionable insights across international markets. My expertise includes using SQL, Looker, and Python to build robust data pipelines, automate analytics, and ensure high-quality, structured data for critical business decisions. I have led multiple projects involving A/B testing, KPI tracking, and process automation, which required meticulous data labeling, annotation, and validation to support reliable experimentation and predictive modeling. I am passionate about translating complex data into clear, actionable strategies and thrive in cross-functional teams focused on building scalable, transparent analytics frameworks. My background in marketplace analytics and operational strategy has equipped me with the skills to manage data quality and structure, ensuring datasets are accurate and ready for advanced AI training or machine learning applications.
