I hold a Master of Science in Management Information Systems with an Information Technology concentration and a Bachelor of Business Administration from Bowie State University. My industry credentials include CompTIA Security+, CompTIA CySA+, Qualys Certified Specialist in vulnerability management, Change Management Associate, and Project Management Specialist certifications, and I am currently working toward CISSP. Beyond certifications, I have spent more than ten years in enterprise IT and cybersecurity, including five years as a Senior Security and Systems Engineer managing vulnerability programs, SIEM monitoring, and incident response, and four years as a Senior Systems Administrator supporting security operations for a large college.

My teaching experience spans more than three years as an adjunct instructor of cybersecurity and networking for university bootcamp programs delivered in partnership with NYU, NJIT, the University of Michigan, the University of Kansas, Independence University, and the University of Central Florida. My students were primarily adult learners and career changers, ranging from their early twenties to their fifties. Instruction was fully online in a live classroom setting, where I led lectures, hands-on labs, and group exercises covering SOC operations, SIEM tools, network fundamentals, and Windows and Linux administration. I also worked with students one on one during office hours to review lab work, prepare for certification exams, and work through difficult concepts.

My tutoring approach starts from wherever the student is and builds toward their specific goal, whether that is passing Security+ or CySA+, completing a course, or landing an IT role. I emphasize hands-on practice over memorization, break complex topics into small steps, and draw on real examples from my security operations career to make abstract concepts concrete. I adapt pace and depth to each student, and I bring patience, structure, and practical insight to every session.

Approved Subjects

Computer Science

Computer Science

I hold a Master of Science in Management Information Systems and have spent 10+ years working as a senior systems engineer and administrator in enterprise environments, in addition to 3+ years teaching university-partnered bootcamp programs. I can help you with computer systems fundamentals, operating systems (Windows and Linux), networking concepts, and scripting with Python, Bash, and PowerShell, all taught from real-world experience keeping large-scale systems running. I've guided adult learners through NYU, University of Michigan, and UCF partnered programs, so I know how to break down technical concepts for beginners and career-changers alike. Whether you're working through intro CS coursework, need help with a specific project, or want practical skills for an IT career, I'll meet you at your level and build from there.
Cybersecurity

Cybersecurity

I'm a cybersecurity instructor and practicing security engineer with 10+ years of enterprise experience and 3+ years teaching cybersecurity and networking through university-partnered bootcamp programs, including courses delivered with NYU, the University of Michigan, and UCF. As a former Vulnerability Management Program Owner, I've led real-world security operations using tools like Qualys, Tenable, Microsoft Defender, and Sentinel, so I teach from hands-on experience, not slides alone. I hold CompTIA Security+ and CySA+ certifications and am currently working toward CISSP, which means I know exactly what these exams expect and how to prepare you for them. I can help you with exam prep (Security+, CySA+), SOC and analyst skills, networking fundamentals, and building the hands-on labs that turn concepts into job-ready abilities.
Information Technology

Information Technology

I'm a senior IT professional with 10+ years managing enterprise environments, including approximately 5,000 endpoints and 300 servers for a national law firm and a multi-campus college system serving 175,000 students. My hands-on expertise spans Windows Server, Active Directory, Microsoft 365 (Exchange, Teams, SharePoint, Intune), networking, virtualization with VMware, and system administration on both Windows and Linux. I've also taught IT and cybersecurity skills for 3+ years through university-partnered programs with NYU, the University of Michigan, and UCF, so I know how to explain technical concepts clearly to learners at any level. Whether you're studying for an IT certification, working through coursework, setting up a home lab, or preparing for your first IT job, I can help you build real, practical skills with tools you'll actually use in the workplace.
UNIX

UNIX

I've administered Linux and Unix-based systems in enterprise environments for 10+ years, including Linux/RHEL server administration across a multi-campus college infrastructure and supporting mixed Windows-Linux environments for a national law firm. My day-to-day expertise covers the command line, Bash scripting, user and permission management, file systems, process management, package management, log analysis, networking configuration, and system troubleshooting. I've also taught Linux administration hands-on through university-partnered bootcamp programs with NYU, the University of Michigan, and UCF, guiding students from their first terminal session to job-ready sysadmin skills. Whether you're learning the command line for the first time, working through a Linux course, prepping for a certification like Linux+, or building a home lab, I'll help you get genuinely comfortable in a Unix environment.
