What I'm looking for

I seek technical roles where I can apply network design and security skills, work with SIEM and Linux systems, and grow in cybersecurity within a collaborative, learning-focused team.

I am a cybersecurity-focused network engineer with hands-on experience in VLAN design, ACL policy implementation, Linux administration, and incident detection using tools like Splunk and Wireshark. I hold an active DoD Secret clearance and CompTIA Security+ (2024), and I apply practical lab and internship experience to secure and optimize network environments.

I have implemented network segmentation, written Bash scripts for automation, and performed log analysis and threat reconnaissance in lab and SOC-style training. I bring attention to operational security from roles with privileged access and a demonstrated commitment to continuous learning and applying security frameworks such as NIST 800-207 and RMF.
