John Calvin
Tyler.
An IT & cybersecurity professional specializing in identity & access management, Microsoft cloud, systems administration, and security operations.
I build technology, systems, and ideas designed to create lasting value.
My work spans cybersecurity, cloud infrastructure, identity, automation, and modern IT operations, with a focus on building secure, resilient systems and solving complex technical problems through practical, scalable solutions.
This site documents the systems I’ve built, labs I’ve completed, tools I’ve developed, and the technical work behind my continued growth in information technology and cybersecurity.
ABOUT
Security foundation. Technical depth.
I’m an IT and cybersecurity professional with roughly six years of experience spanning security operations, physical security, access control, identity, technical support, and cybersecurity. My career began with three years in physical security and security operations, where I developed hands-on experience with access control, incident response, credentialing, security procedures, and protecting people and environments.
Over the past three years, I’ve expanded that foundation into IT infrastructure, identity and access management, cloud administration, and security operations. My work includes Active Directory and Entra ID, Microsoft 365, Windows administration, IAM, networking, security monitoring, troubleshooting, and user lifecycle management—reinforced through hands-on labs and public technical projects.
I’m especially interested in how identity, infrastructure, and security intersect. I build systems, automate repetitive workflows, document what I learn, and develop software concepts and digital products designed to solve practical problems.
