01 // About

More than a
resume entry.

I'm a cybersecurity & network administrator who learns by building, breaking, and defending real infrastructure — not just reading about it. I captained my college CCDC team to a 3rd-place regional finish, defending live services under active attack while keeping them online.

My role is hands-on: hardening systems, watching the wire, and responding to incidents in real time. That kind of pressure rewires how you think about security — every assumption gets tested.

Off the competition floor I run a multi-site homelab — a Proxmox cluster, an Active Directory enterprise lab, VPNs, firewalls and monitoring — the same stack I document at docs.4rji.com and ship as the open-source 4rji binaries. Nothing goes live until it's rock solid.

03 // Experience

Where I've put in
the work.

I may not have a long list of job titles yet — but I've spent years building, breaking, defending, documenting, and automating real technical environments. It comes from hands-on projects: cyber-range development, homelab infrastructure, CCDC leadership, security tooling, and technical writing.

CCDC Team Captain

Led training and lab development for competition prep — Linux hardening, Windows services, incident response, logging, networking, and service validation.

Cyber Range / Lab Builder

Designed practical labs for students and teammates: dashboards, vulnerable services, Linux & Windows hosts, Syslog, RADIUS, TACACS+, web, FTP, and scoring-style validation.

NALA / Zeek Monitoring

Built security-visibility tooling on Zeek logs and network telemetry with AI-assisted analysis — DNS, HTTP, SSL, connection logs, threat intel, and alert summarization.

Homelab Infrastructure

Built and run a personal lab on Proxmox, Docker, VPNs, firewalls, Linux servers, monitoring, storage, and self-hosted services.

Network & VPN Projects

WireGuard, OpenVPN, pfSense, OPNsense, VLANs, DNS resolvers, tunnels, and reverse proxies for secure remote access and segmented labs.

Security Tooling & Automation

Scripts and tools that automate workflows, collect system info, analyze logs, generate reports, and speed up repetitive security tasks.

Web & App Projects

Web tools, dashboards, Electron apps, and documentation pages focused on cybersecurity, infrastructure, and technical learning.

Offensive Security Practice

Documented labs across Active Directory attacks, privilege escalation, web vulns, tunneling, reverse shells, C2 concepts, enumeration, and exploitation.

Defensive Security Practice

Wazuh, Splunk alerts, Filebeat, auditd, Sandfly, Linux forensics, Zeek, log forwarding, and system-hardening workflows.

04 // Education

Building the
foundation.

Formal credentials behind the hands-on work — every degree, diploma, and certificate verifiable.

05 // Development

Always
leveling up.

I stay current through security, open-source, and technical conferences focused on cybersecurity, infrastructure, AI/security, and defensive tooling.
