DATA MODELING & VISUALIZATION
with POWERBI

NY School Performance Dashboard

This interactive Power BI dashboard provides users with academic data about how individual NYS schools performed on state exams (Regents).I created it by combining several publicly available datasets and modeling the data into a star schema. I used DAX code to create a couple of the attributes.

This dashboard is interactive, but it's designed to be easily transmitted as a pdf as well. Underlying data pertains to several key aspects of a nonprofit's viability.


INTERACTIVE EXCEL DASHBOARD

CALL CENTER DATA ANALYSIS

I designed this interactive Excel dashboard with some modern flare. The underlying data represents a company's customer service call center information. Download full file below.

DATA ENGINEERING + VISUALIZATION WITH PYTHON

NONPROFIT INDUSTRY ANALYSIS

Data for this project came from the BMFF, a public tax database with millions of rows. It's too big for Excel, so I wrote a Python script to query the data and visualize it. I used Canva for the final brochure design. Download and skim at your leisure!
