Gillen CTech
Twenty-plus years bridging enterprise IT infrastructure and hands-on software development. I keep the systems running — Active Directory, imaging, ServiceNow, Okta, Epic/Citrix environments — and I build the tools that make them easier to run.
Two sides, one instinct
Infrastructure & Support
Enterprise application support and identity management — Active Directory, Okta, ServiceNow ticketing, Epic/Citrix environments, imaging, and on-site hardware deployment across large organizations.
Full-Stack Development
ASP.NET Core MVC applications backed by SQL Server and Entity Framework Core — from multi-tenant SaaS platforms to internal tools built to solve real, specific problems.
