Strategic IT Director & Infrastructure Architect
“I align technology initiatives with long-term business goals, driving operational efficiency and leading transformative IT projects.”
I hold a Bachelor of Science in Computer Information Systems from DeVry Institute of Technology and began my career as a developer focusing on dBase III, FoxBase/Pro, and Clipper. Over thirty years, I’ve progressed to strategic IT leadership roles—most recently as Technical Director, Infrastructure & Data Center Operations Manager at 84.51° (a Kroger Company).
At 84.51°, I directed enterprise-wide infrastructure strategies, led teams of 4–13 engineers, and managed storage platforms (Dell ECS, PowerScale, Oracle ZFS, PureStorage, Synology) to ensure high availability and disaster recovery readiness. I drove automation with Ansible, PowerShell, and Bash to standardize operations and achieved NIST SP 800-53 compliance to bolster security.
Earlier, I founded agh3 IT Services LLC (2006–2016) in Shorewood, IL, providing end-to-end IT consulting for small businesses and non-profits—designing secure networks, implementing proactive monitoring, and delivering website development and offsite backup solutions.
Prior to that, I worked at various software consulting firms building and managing their network infrastructure. I also worked at TLC Netowrks where I provided a wide range of IT services for small to medium sized businesses.
