I am a detail-oriented data analyst with hands-on experience preparing, cleaning, and validating large datasets for analytics and business intelligence solutions. My expertise in SQL, Python (Pandas, NumPy), and data visualization tools like Power BI allows me to ensure high data quality and integrity, which are crucial for accurate data labeling and AI training data pipelines. I have managed and processed customer and retail datasets with 10K+ records, implementing robust data cleaning, standardization, and schema validation to maximize data completeness and reliability. My projects have involved segmenting users, handling missing values, and building dashboards that rely on precise and well-structured data, skills directly applicable to data annotation and preparation for machine learning workflows. I am passionate about transforming raw data into actionable insights and supporting AI development through meticulous data preparation and annotation.
