About Me

Hello, I'm Cory Weiner,

I grew up in Omaha Nebraska, where I’ve discovered and built on my passion for technology and business. From a young age I was always fascinated by coding and design work. At age 13 I created my first website where I authored tutorials on Photoshop and web design.

During high school, and throughout college, I began to take on freelance jobs creating websites for local businesses. I attended the University of Nebraska, Lincoln, where I majored in Accounting, Finance, and Economics. I graduated in 2013 with the highest distinction of Chancellors Scholar.

While my focus of study was on business, throughout my time in college I continued to build on my passion for technology. I took on an internship at the American Civil Liberties Union (ACLU) where I was able to put my development skills to the test working on revamping their salesforce platform used to intake data for requests for legal services.

Around the same time, I competed with a small group in the Peter Thiel 20under20 competition, where our group made it to the semi-finals with a business plan to create an RFID service provider for inventory management and process automation.

Upon graduating, I took a job as a financial analyst with Gallup, nationally recognized for their polling and analytics platforms. Here I worked heavily with Oracle platform OBIEE where I developed reporting and process automation for upper management. After several years in this position, I knew I wanted to be more involved in the technology side of the business, and I migrated to a data warehouse engineering role. This was a great role as it allowed me to merge my love for technology with my background in business and analytics.

Currently I serve as director of technlogy for White Castle Roofing, one of the largest residential and commercial roofing contractors in the Midwest. Here I am responsible for leading all development and technology iniatives. Recently I managed a year long ERP migration to Oracle Netsuite.

Outside of my job, one of my passions is working on personal web development projects. You can find some of those projects in the portfolio section below. When I’m not working, you can probably find me camping, kayaking, hiking, or playing a game of competitive Overwatch.

I’d love to work with you on your next project. Let’s talk.
