About

For a deeper dive into my work and interests, feel free to explore my personal networking blog at www.packetswitch.co.uk I'm a Network Engineer with 8+ years of experience and a strong passion for Cloud and Automation. Based in London, I thrive in diverse, dynamic, and challenging environments, continuously looking to broaden my skill set. My current focus is heavily on Python, Automation, and Cloud, as these technologies are shaping the future of Networking. Over the years, I've gained hands-on experience with a wide range of vendor products, including Cisco, Palo Alto, Meraki, Fortinet, Check Point, Juniper, and more. While my AWS (Advanced Networking) and Juniper (JNCIS) certifications have expired, I continue to engage actively in professional development to keep my skills current. I hold active CCNP Enterprise and Security certifications. Technologies I Work With: - Cisco ISE (Wired/Wireless NAC, Guest Services, TACACS+) - 802.1X (EAP-TLS, EAP-TEAP) - Cisco (Catalyst, Nexus, Routers) - NetDevOps (Python, Ansible, Terraform, REST API) - Firewalls (ASA, Check Point, Fortigate, Palo Alto) - AWS Network Services (VPC, TGW, GWLB, Lambda, Route 53) - Prisma Access SASE - Jenkins - Docker - Git
