• Implement network monitoring solutions and lead incident response for network outages and performance degradation
• Design, deploy, and manage enterprise VoIP and SIP infrastructure including IP-PBX systems, SIP trunking, session border controllers (SBCs), and unified communications platforms for banking, telecom, and government clients
• Configure and optimize SIP endpoints, dial plans, call routing policies, and QoS mechanisms to guarantee voice quality across multi-site enterprise LAN/WAN environments, while troubleshooting signaling issues using protocol analyzers such as Wireshark and Sngrep
• Enforce VoIP security best practices including SIP authentication, TLS/SRTP encryption, and toll fraud prevention, and integrate voice platforms with enterprise collaboration tools such as Microsoft Teams Direct Routing and Cisco Webex Calling
• Conduct network audits and capacity planning to support clients' business growth and digital transformation roadmaps
• Design and enforce network segmentation, VLANs, VPNs, and zero-trust network access (ZTNA) architectures
• Collaborate with system administrators, security teams, and client IT departments on integrated infrastructure projects
• Produce detailed network documentation including topology diagrams, IP addressing schemas, and change management records
