I can do exactly what you need. I'm a computer science professional with extensive experience in math, as well as automation of data acquisition, processing, analysis, and presentation in Excel using custom dashboards, macros (VBA scripts), pivots, filters, and other advanced tools. I've done a lot of similar work. Please see reviews on my profile. It would be my pleasure to complete your project.
