About

Results-driven Data Analyst with experience in building ETL pipelines, transforming large datasets, and delivering business insights. I have worked extensively with Python, SQL, Snowflake, AWS Lambda, and Power BI to design automated data workflows and create impactful dashboards for decision-making. At NIQ, I was involved in analyzing structured and semi-structured data, defining business requirements, and converting raw data into meaningful insights that support strategic growth. I enjoy solving complex data problems, optimizing processes, and collaborating with cross-functional teams. I am detail-oriented, analytical, and continuously learning to expand my expertise in data engineering and business analytics. I aim to bridge the gap between technical data solutions and business strategy.
