ABOUT JOHN MATHEWS
I’m a technically curious systems troubleshooter currently transitioning into IT and security-focused roles.I hold GIAC GFACT and GSEC certifications and have recently refreshed my command-line skills after many years away from formal IT. I’m particularly drawn to environments where practical problem-solving, systems understanding and clear, methodical thinking are essential.My strengths include:• Structured troubleshooting• Pattern recognition and root cause analysis• Clear communication of technical issues• Rapid, self-directed learning• Remaining calm and focused under pressureI am currently building hands-on experience in IT support and infrastructure as a foundation for longer-term progression into digital forensics and incident response.I value depth over noise, practical competence over process for its own sake, and working within teams where careful thinking and reliability are respected.If you work in a technically focused environment and value steady, thoughtful problem-solvers, I’d be glad to connect.
