The Best Business Intelligence Portfolio on the Internet

My name is John DeLizza and have been professionally working with data for over eighth years! I am currently a Senior Business Intelligence and Reporting Analyst for Dyson America on the Strategy, Data Science, and Analytics team under Finance. My primary tools are Tableau, SQL, R, Python, and when all else fails, Excel.

I have worked with data since 2009 when I got an internship at a local medical device consulting company in Los Altos, CA. This company, First Light Health, consulted major healthcare brands such as Abbott, Samsung Health, and several local startups. on market strategy and product development. My tasks were simple – gather or input marketing survey data, perform basic analysis, and present findings.

This two-summer opportunity led me towards studying Statistics at Loyola University Chicago and another internship at Inspirotec, a local Chicago medical device startup. Here, I had my first foray into statistical analysis in a professional setting and provided a product pricing recommendation based on the Van Westerndorp pricing model built on survey data. I went on to graduate with a degree in statistics in 2016.

In the years since, I’ve had the privilege to work at CareerBuilder, Empire Today (1-800-588-2300), and Dyson. Ultimately, my work evolved from performing business analytics to business intelligence as I found great joy in automating reporting and never shied away from a challenge. This has led me to develop skills in VBA to automate Excel, R to serve as middleware for crude ETLs, SQL to speak to databases, and ultimately Python to serve as middleware for slightly less crude ETLs. Standing on top of it all is Tableau, which optimally delivers the only the most vital information from these foundations in an optimal way designed for each end user. This portfolio is a compilation of those highest level outputs. Absent from it is the thousands of lines of SQL, R, and Python code that has enabled it.

Thank you for your time.
