I am able to use formulas in Excel to calculate essential metrics like cost per click (CPC), click-through rate (CTR), cost per sale (CPA), cost per thousand impressions (CPM), and profit per sale. These data points hold significance in determining the most efficient and cost-effective advertising strategies.

My Tableau skills include using Tableau Prep Builder to clean and organize data, performing tasks such as field deletion, value grouping, data splitting, and applying filters. I have experience creating joins between datasets and exporting refined .csv files. Additionally, I have utilized Tableau Desktop to analyze survey data on student demographics, creating visualizations like maps, scatterplots, and bar charts. In another project, I conducted an AirBnb analysis, employing visualizations such as treemaps, heatmaps, line charts, and stacked bars to compare prices based on various factors. I also created interactive dashboards using filters and parameters.
