IT & Cybersecurity Professional with 20+ years of experience in infrastructure, systems administration, and technical operations.
I bring a strong background in Windows/Linux environments, Active Directory, networking, virtualization, and cloud-connected systems, with a growing focus on cybersecurity, security operations, and risk-aware IT practices.
- Cybersecurity fundamentals and security operations
- Network and system security (routing, switching, firewalls, access control)
- Windows Server, Active Directory, and Linux administration
- Cloud and hybrid environments (Azure fundamentals)
- Applying frameworks like NIST CSF, CIS Controls, and COBIT in practical scenarios
I believe:
- Frameworks provide structure
- Real-world labs and troubleshooting build actual skill
Most of my work focuses on bridging the gap between theory and real-world IT environments, especially in areas like:
- system hardening
- access control
- operational risk awareness
- secure configurations
I’m currently building hands-on labs and practical projects focused on:
- Active Directory security and access control
- Network security and segmentation basics
- NIST Cybersecurity Framework practical mapping
- Linux server administration and hardening
More projects coming soon as I continue building out my cybersecurity portfolio.
