From June 2023 to September 2023, I performed data analysis using Excel and SQL. I conducted exploratory data analysis on various datasets, built interactive dashboards with Tableau Public and Excel, and worked SQL for end-to-end data processing, including creating databases, and tables, and using joins and cohort views. Using information from IMDb movie ratings, Instagram analytics, car attributes affecting pricing, and a bank loan case study, I predicted the most likely default clients without altering the data's accuracy.
