About me

I am a Security Engineer with over 5 years of experience implementing advanced security solutions such as SentinelOne, Cortex XDR, and Workspace ONE. My expertise lies in SOC operations, where I have worked both as an analyst and an incident responder, ensuring robust security postures for various organizations. I have hands-on experience integrating security tools to enhance operational efficiency and have implemented Linux authentication systems like Samba to secure workflows effectively.

Throughout my career, I have led endpoint security deployments for large financial institutions, developing automated threat detection rules that significantly reduce false positives. I have also integrated XDR platforms with SIEM systems to provide unified monitoring and improved threat visibility. My role often involves fulfilling multiple responsibilities, including SoC analyst and incident responder duties.

In addition to my practical experience, I hold several certifications, including SentinelOne Tech Accreditation Applied, TXOne Certified Solutions Specialist, and VMware Certified Professional – Digital Workspace. These certifications complement my technical skills and demonstrate my commitment to staying current with industry standards.

Previously, I worked as a Systems Engineer, where I implemented and supported Unified Endpoint Management (UEM) solutions like Workspace ONE across governmental and financial sectors. I have experience managing multiple operating systems, including Android, iOS, macOS, and Windows, and have developed secure kiosk environments for digital signing purposes.

My educational background includes a Bachelor of Science in Computer Science with a specialization in Security from Portsmouth University. My studies focused on networking, databases, programming, ethical hacking, and forensic investigation. My dissertation explored the impact of honeypots on intrusion detection systems and network latency.

I am passionate about leveraging my skills to protect organizations from evolving cyber threats and continuously improving security operations through innovative solutions and automation.
