I present here only three distinct projects that highlight the versatility of my data processing capabilities. The first project focuses on data unification and cleaning related to a criminal network study, where I employed various techniques to transform fragmented datasets into cohesive insights. The second project revolves around sales performance reporting, utilizing advanced metrics to analyze trends and drive strategic decision-making. Lastly, I developed a customer transaction analysis and fraud detection system using SQL and Python. This project aims to identify suspicious activities and ensure data integrity, providing actionable intelligence for preventing potential fraud. Each endeavor showcases my proficiency in handling complex data pipelines and leveraging analytics to solve practical challenges.
