jT | System Administration, Cybersecurity, and Network Architecture

40+ years of technical innovation and expertise spanning System Administration, Ethical Hacking, Social Engineering, and Penetration Testing.

Executive Summary

I am a highly experienced technology professional, known as jT, with a career dating back to the mid-1970s. My foundational interest in computing—sparked by my father, an engineer—began with a Commodore 64 and evolved into a deep-seated passion for understanding and securing complex systems. Driven by curiosity, I have cultivated a diverse skill set across multiple generations of technology, focusing on network design, systems optimization, and proactive security measures.

Professional Journey & Core Competencies

Foundational Development (1970s – 1990s)

My journey began with hands-on hardware and software development, progressing from building early-model PCs (286 systems) and coding in GWBasic to mastering programming languages including C, C++, Cobol, Pascal, and Basic. This era also involved rigorous exploration of system architectures and human-centric security vulnerabilities, laying the groundwork for my expertise in Social Engineering and Reverse Engineering.

Pioneering Network and Systems Administration

My early career spanned varied and demanding technical roles:

• Systems Integration: Developed proprietary scheduling applications for security firms.

• Compliance & Network Infrastructure: Implemented ISO 9002 quality management standards and established initial network architecture for a major coal company.

• Telecommunications: Served as the Head Technician and Support Center Manager for a local cell phone provider. I was instrumental in establishing one of Southern WV’s first Internet Service Providers (ISP) and developed advanced intrusion detection methods.

• State-Level Network Management: After acquisition, managed large-scale state networks and engineered an innovative Out-of-Band Management (OOBM) system, garnering attention from key industry leaders like Cisco and 3Com.

Specialization in Cybersecurity and Ethical Hacking

I achieved my CCNA certification and dedicated significant focus to complex Wireless Networking and firewall architecture. My commitment to security escalated in the early 2000s, where I formally adopted Ethical Hacking practices. I utilized specialized tools to conduct comprehensive wireless network mapping and vulnerability assessments, actively collaborating with local businesses to enhance their system security. This experience fueled a deep understanding of penetration testing methodologies and responsible disclosure protocols.

Current Role & Expertise

For the last 20+ years, I have served as a dedicated System Administrator for a global corporation, ensuring the stability, security, and scalability of critical infrastructure. My primary focus remains on continuous learning and applying decades of practical experience to modern challenges.

“Learn something new every day, and you will never get bored.”

Looking Ahead

I am actively focused on contributing to the industry by sharing practical insights and experiences through professional development channels. Future content will cover:

• Detailed case studies on Social Engineering methodologies and defense strategies.

• Training seminar highlights on corporate security awareness.

• In-depth accounts of Reverse Engineering projects.

I am available for consultation and collaboration on advanced system administration and cybersecurity challenges.
