Summary
I am an experienced IT and Network Security Professional with over two years of hands-on expertise in designing, implementing, and managing secure network infrastructures. My career has focused on network security, endpoint protection, and compliance with international standards such as ISO 27001 and NIST.
I specialize in configuring and managing advanced security tools like Palo Alto Firewalls, FTD, FMC, and F5, as well as implementing IPsec VPNs, network segmentation, and VLANs to enhance security and performance. I have a strong track record in vulnerability management using tools like Qualys, SIEM solutions (including Splunk), and endpoint security with Sophos Antivirus and DLP solutions.
Additionally, I have experience in troubleshooting complex network issues, managing Cisco Core Switches, and ensuring secure remote connectivity through Cisco AnyConnect and Pulse Secure. My work has consistently improved network reliability, reduced downtime, and strengthened defenses against cyber threats.
I am passionate about staying updated with the latest security trends and technologies, and I thrive in roles that require proactive risk management and robust security frameworks.
