About Mohamed-Reda

Hello and welcome to my profile!

Driven by a growing passion for the administration and security of IT infrastructures, I have accumulated considerable experience in this rapidly evolving field. As a technical referent within teams, I have had the opportunity to share my knowledge in security and networks, training my colleagues on certain key aspects of this domain, which has helped to improve their skills and strengthen the overall security of systems.
I am determined to improve infrastructure security while fostering a cybersecurity culture within teams. Thanks to my combination of technical expertise and continuous learning, I ensure optimal data protection by creating efficient and resilient systems.
I have acquired a wide range of technical skills, particularly in networks and security, as well as in firewall management and traffic analysis. I also have expertise in operating system administration, whether for Windows Server or Linux distributions. My experience also extends to virtualization and private cloud structures, such as at Orange Business Services, where I worked in HDS (Health Data Hosting) hosting.
I am solution-oriented and always strive to propose innovative improvements.
My intellectual curiosity leads me to stay informed about the latest technologies and industry trends.

If you are looking for a professional who can transform your technical challenges into effective solutions, I am here to help. I look forward to collaborating with you to achieve your goals!
