Larry Mullen



Friendly Connector   Focused Advisor   Visionary Artist

When Larry joined Cornerstone Data, he took our team to a whole new level. A talented database developer, experienced QA leader, and a reliable development manager – our clients know they are in good hands when he is assigned to a project.

Prior to joining us, Larry was a Business and Systems Analyst at Cargill, where he was tasked with developing both technical and functional requirements for software and databases that replaced legacy systems in the company. He also had the opportunity to sharpen an innate skill he possesses for user design (UX). These responsibilities required working with various stakeholders to ensure he understood their processes and captured their information when designing the new system.

Larry also enjoyed a stint working for Poet Ethanol Products designing custom software, testing it, and supporting their internal users. This experience allowed him to understand the lifecycle process for software development and cultivate his customer service skills.

Alex Miller


June 2016 - May 2017

Just before his junior year at Wichita State University, Alex joined our team to help us on a new client project. He immediately exceeded all of our expectations. His interest in the work and his drive to do well allowed him to quickly learn new skills and employ them on several projects.

In the year he was here, he learned how to create a database and set it up with the proper schema and stored procedures. He also figured out how to get SQL Server Report Services working and began creating reports for our client. Alex’s work ethic, team spirit, and ambitious attitude will carry him far.

Tyler Griggs


Summer 2017

Tyler spent a summer as part of the Cornerstone Team after completing his Freshman year at Harvard University. That’s right…Harvard University. Tyler came highly recommended to our team before he even started college because one of our developers heard he was interested in development and he had scored a perfect 36 on his ACT. Since we love smart people who work hard, it was clear we needed Tyler on our team.

During Tyler’s internship, he created an internal wiki using open source software and transformed our directory-style “How-To” documents into a searchable, editable, secure website so team members could quickly find the information they needed. Additionally, Tyler helped develop this very website you are looking at right now.
