Security thinking backed by practical IT experience.

My cybersecurity education shapes how I approach everyday technical problems. Performance, reliability, and security are connected, so I look beyond the immediate symptom to understand the system behind it.

I use the same process whether I am troubleshooting a Windows computer, configuring a server, or working through a security lab: identify the problem, test assumptions, document the evidence, and explain the solution clearly.
