As an intermediate professional in computer networking and security, I bring hands-on experience in managing and securing network infrastructures with a focus on reliability and protection against threats. My expertise includes working with Cisco technologies, such as configuring routers, switches, and setting up secure VLANs. I am skilled in network troubleshooting, performance optimization, and deploying basic security measures like firewalls and intrusion detection systems.Additionally, I have experience in penetration testing, where I analyze vulnerabilities, perform security assessments, and suggest actionable improvements to strengthen systems. My understanding of network protocols (TCP/IP, DHCP, DNS) and virtualization tools enables me to optimize both physical and virtual networks effectively.While still building advanced expertise, I am capable of addressing core challenges in network design and security, ensuring compliance, data integrity, and smooth communication. My goal is to continue refining my skills while delivering practical, impactful solutions tailored to employers' needs.
