About George

I am a senior Cybersecurity professional with 7+ years of Developing and Offensive Security experience, ready to provide services such as:
• Web Pentesting
• Chrome Extension Security Auditing
• Android Mobile Application Pentesting
• Secure Code Auditing
• Infrastructure (including AWS) Pentesting and Hardening
• Social Engineering Exercises

I have worked as a developer, and I now am an Offensive Security engineer with OSCP. I specialize in Web Applications, Chrome Extensions and Secure Code Audits. I have also worked with and completed security projects on AWS infrastructure and services, Android Mobile Applications and performed numerous Social Engineering and Red Teaming projects with numerous clients.

I have worked in high-profile companies such as Cisco, Halborn and Odyssey Cybersecurity. My responsibilities included the organization and execution of web, network and mobile application vulnerability assessments, social engineering, red teaming exercises and incident responses.
Furthermore, as a Senior Cybersecurity Analyst I was responsible for internal tool development, such as social engineering infrastructure and Trojans used for our exercises.

I consider myself to be self-motivated and have learned to tackle any task given to me. I am keen on delivering excellent work which is reflected in high-detail reports.
