Cisco Routing & Switching
Cisco routing and switching platforms provide the foundation for enterprise networks worldwide with industry-leading reliability, security, and advanced features including BGP, OSPF, VLANs, QoS, and software-defined networking.
VPN (Virtual Private Network)
VPN technology creates secure, encrypted connections over public networks, enabling remote access, site-to-site connectivity, and privacy protection. With extensive experience in VPN architecture and implementation, I design secure network solutions for distributed organizations.
BGP (Border Gateway Protocol)
BGP is the routing protocol of the Internet, enabling autonomous systems to exchange routing information and make path decisions. With deep expertise in BGP, I architect scalable, resilient network solutions for multi-cloud, hybrid cloud, and enterprise environments.
DNS (Domain Name System)
DNS is the hierarchical distributed naming system that translates human-readable domain names into IP addresses, serving as the Internet's phonebook. With extensive DNS expertise, I design resilient DNS architectures, implement advanced features like DNSSEC and GeoDNS, and optimize DNS performance for global applications.
TCP/IP (Transmission Control Protocol/Internet Protocol)
TCP/IP is the foundational protocol suite powering the Internet and modern networks, providing reliable end-to-end communication across diverse networks. With deep TCP/IP expertise, I design network architectures, troubleshoot complex connectivity issues, and optimize protocol performance for demanding applications.
SMTP (Simple Mail Transfer Protocol)
SMTP is the Internet standard protocol for email transmission, enabling mail servers to send, receive, and relay email messages. With extensive email infrastructure experience, I architect scalable mail systems, implement security controls (SPF, DKIM, DMARC), and ensure reliable email delivery for organizations.
