Hi, I’m Anna 👋
I’m a Junior Infrastructure & Security Engineer and BSc Cyber Security student at the University of Essex Online, building hands-on experience across infrastructure, networking, systems administration, and defensive security.
I’m particularly interested in understanding how systems and networks work in real environments — from troubleshooting connectivity and infrastructure issues to securing systems, analysing traffic, and investigating security events.
🔧 Current Focus
- Infrastructure and network troubleshooting
- TCP/IP, subnetting, VLANs, routing and switching
- Windows and Linux administration
- Network and endpoint security
- Wireshark and packet analysis
- PowerShell and Python automation
- Security monitoring and Blue Team fundamentals
- Clear technical documentation and reproducible lab notes
- CompTIA Network+ preparation
