Network & Security Architect (SASE, Firewalls, Routing & Switching, Wireless, PAM, IAM, MFA, VPN, WAN-OP, SIEM/SOAR, EDR/XDR) Network & Security Architect with 10+ years delivering design, deployment, and operationalization of enterprise networks and security stacks (Cisco, Juniper, Aruba, Fortinet, HPE, Huawei/H3C, VMware, Veeam). Proven at delivering secure, scalable, highly available solutions—SASE/Zero Trust, firewall consolidation, multi site wireless, SIEM/SOAR and EDR/XDR integrations—with architecture artifacts, automated playbooks, validation testing, and operational handover for SOC and NOC readiness. Projects Delivered 1. Enterprise Core Routing and Switching Modernization Campus and Data Center Redesign for 2,000 Users: Full campus and data center network redesign and deployment — logical and physical topology, IP addressing plan, VLAN/trunking, STP tuning, OSPF/BGP/MPLS routing, HSRP/VRRP high availability, route redistribution, interface optimization, and configuration templates with cutover and rollback plans. Technologies: Cisco, Juniper, Aruba, HPE, Dell, Huawei/H3C, Allied Telesis, Extreme, D Link, industrial grade switches. Outcome: 99.99% availability, reduced broadcast domains, and deterministic QoS for voice and video. 2. Multi Site Wireless Network Rollout Multi Site Wireless Network Rollout: End to end wireless deployment across 25 sites — RF/site surveys, capacity and channel planning, AP placement, controller and standalone configurations, SSID and 802.1X/RADIUS security design, QoS and roaming optimization, NAC integration and monitoring for operational handover. Technologies: Cisco, Aruba. Outcome: Consistent coverage, voice handoff latency <50 ms, documented runbooks and operational readiness. 3. Firewall Consolidation and Perimeter Hardening Consolidation and standardization of firewall estate: architecture, policy matrix, IPsec/SSL VPNs, IPS/IDS tuning, SSL inspection, NAT, HA/clustering, centralized logging and forensics. Technologies: Fortinet, Cisco ASA/FTD. Outcome: reduced policy sprawl and faster incident investigations. 4. SASE and Zero Trust Implementation Phased SASE rollout and Zero Trust controls: SD WAN, SWG, CASB, ZTNA, identity aware policies, micro segmentation, service insertion, and telemetry for enforcement. Outcome: secure remote access, reduced lateral movement, improved branch performance. 5. SIEM, SOAR and EDR/XDR Deployments SOC enablement with centralized telemetry and automated response: log ingestion and normalization, detection engineering, threat intel integration, SOAR playbooks, endpoint telemetry, automated containment, and forensic capture. Outcome: reduced MTTD, automated containment, improved forensic readiness. 6. Virtualization, Backup and AD Resilience VMware ESXi cluster design, Veeam backup/replication, Active Directory hardening and HA, DNS/DHCP optimization, and SQL Server HA guidance. Outcome: met RTO/RPO targets and simplified failover procedures. 7. NAC and Identity Integration 802.1X/RADIUS/TACACS+ deployment, posture checks, RSA MFA integration, and onboarding workflows to enforce device compliance and secure access.
