Hi, I'm Rizwan Ahmad.

Early-career Network & Systems Administrator with a Security Mindset.

Tech-Savvy. Detail-Oriented. Eager to Make an Impact.

I design and deploy virtualized environments using Windows Server, Active Directory, and pfSense to simulate real-world enterprise networks. My background blends hands-on networking labs, firewall configuration, and system hardening with strong fundamentals in cybersecurity. I’ve built and documented projects involving VLAN segmentation, secure VPN tunnels, GPO automation, and vulnerability assessments using tools like Wireshark, Nessus, and OpenVAS. With a focus on stability, security, and automation, I’m driven to maintain reliable IT systems and contribute to resilient network infrastructure teams.

What I Do

I work at the intersection of networking, systems administration, and security.

I’ve designed and deployed Active Directory environments, configured VPNs using WireGuard and OpenVPN, and built pfSense firewalls to simulate enterprise-grade network segmentation. My technical toolkit includes Windows and Linux servers, virtualized lab networks, and monitoring tools like Wireshark and Splunk.

Through hands-on labs and client-facing support, I’ve gained real-world experience in diagnosing network issues, enforcing group policy, and securing system access. I also hold CompTIA Security+ and A+ certifications and am currently preparing for the CCNA to deepen my routing and switching expertise.
