Four pillars of senior network engineering.

Hands-on execution across the full network lifecycle — from core switching fabrics to managed operations. Every engagement delivered by a senior engineer, no junior handoffs.

Enterprise network switch with cables
Pillar 01

Data Center Fabrics & Core Switching

High-availability switching architectures engineered to eliminate single points of failure across enterprise and industrial data centers.

  • Nexus Data Center Topologies — Configuration and support of Cisco Nexus 9K, 7K, 5K, and 2K series fabrics utilizing Virtual Port Channel (vPC) and redundant server switch stacks.
  • 3-Tier & Collapsed Core Campus — Core, Distribution, and Edge implementations using Cisco Catalyst 9500, 9300, 9200, 4500, and 3850 platforms.
  • High-Availability Protocols — Cisco Virtual Switching System (VSS), HSRP / VRRP default gateway redundancy, StackWise clustering.
  • Advanced Dynamic Routing — L3 Inter-VLAN routing, BGP, OSPF, and VRF segmentation across enterprise data centers and campus backbones.

What You Get

  • Validated, staged configuration across every device in scope
  • Visio L2/L3 topology with data flow and rack elevations
  • Pre-cutover, during-cutover, and post-cutover runbooks
  • Change-board submission and risk-scored defense
  • Rollback plan validated in lab, not theorized
  • As-built documentation handed off on completion

When You Need This

  • Existing fabric is end-of-life or approaching it within 12 months
  • Single points of failure identified in audit or review
  • New data center buildout or migration in flight
  • M&A integration requiring rapid network convergence
  • BGP / OSPF redesign after a major topology change

Enterprise next-generation firewall
Pillar 02

Perimeter Security & Dynamic Access Control

Zero-trust network access, robust firewall policies, and granular traffic segmentation for environments where security is non-negotiable.

  • Next-Generation Firewalls (NGFW) — Multi-site policy design, NAT rules, and VPN gateway deployments on Palo Alto Networks (PA-5020, PA-850, PA-220), Cisco Meraki MX, Fortinet FortiGate, and Cisco ASA.
  • Identity & Access Control (Cisco ISE) — Wired and wireless 802.1X authentication, endpoint device profiling, and posture assessment.
  • Network Access Control (NAC) — Specialized industrial packet analyzers and sniffing tools for dynamic 802.1X Lite and Full endpoint verification.
  • Network Isolation — Secure segmentation between corporate offices, industrial control systems (ICS / SCADA), cleanrooms, and testing lab networks.

What You Get

  • Firewall policy designed for least-privilege, default-deny posture
  • NAC policy with endpoint profiling and posture enforcement
  • Segmentation between corporate, ICS, lab, and guest networks
  • VPN topology with HA and proper key management
  • Audit-ready rule documentation and justification
  • Compliance mapping (PCI, HIPAA, SOX, CMMC) where applicable

When You Need This

  • Audit findings require tightening of firewall and NAC policy
  • ICS / SCADA systems need to be isolated from enterprise traffic
  • Compliance framework (PCI / HIPAA / CMMC) is being implemented
  • Endpoint visibility into the network is insufficient
  • Existing firewall ruleset has grown unwieldy and needs review

Enterprise wireless access point
Pillar 03

Campus Refresh, WAN & Enterprise Wireless

Seamless lifecycle execution and high-performance branch connectivity — delivered in maintenance windows, never against production schedules.

  • MDF / IDF Closet Modernization — Complete physical layer (L1) structured cabling audits, rack cleanup, and logical switch migrations.
  • Enterprise MPLS & WAN Backbones — Cross-border WAN topologies utilizing MPLS, BGP, and OSPF across Cisco ISR 4300 and ASR 1000 series routers.
  • Enterprise Wireless Deployments — Centralized WLAN architecture using Aruba Wireless (Mobility Conductors, A7024 Controllers, AirWave) and Cisco Meraki MR cloud-managed APs.
  • Zero-Downtime Cutover Execution — Meticulous maintenance window planning to prevent disruption to production and manufacturing lines.

What You Get

  • MDF / IDF physical layer audit with rack elevation drawings
  • Pre-staged switch configurations for parallel cut
  • Maintenance window plan with explicit rollback triggers
  • Wireless site survey and AP placement validation
  • WAN topology with HA and failover validation
  • Standardized configuration templates for ongoing operations

When You Need This

  • Multi-site EOL refresh program in flight
  • Manufacturing or operations environment with strict uptime SLAs
  • Wireless coverage gaps or capacity issues reported by users
  • WAN consolidation or MPLS migration in progress
  • Distributed closets with inconsistent standards and documentation

Pillar 04

Discovery, Documentation & Managed Operations

Bringing clarity, compliance, and structured operational management to complex networks — including legacy environments with no accurate documentation.

  • Baseline Network Discovery — Thorough auditing of undocumented or legacy network topologies to map physical connections and logical traffic flows.
  • Comprehensive Microsoft Visio Topologies — Architectural diagrams, L2/L3 data flow schematics, and rack elevation layouts for internal and compliance audits.
  • Performance & Health Monitoring — Real-time bandwidth, interface health, and SNMP / MRTG tracking using SolarWinds and PRTG.
  • Operational Discipline — End-to-end management of Tier-2/3 ticketing queues, Configuration Compliance Audits, and hardware asset lifecycle tracking.

What You Get

  • Complete physical and logical topology map
  • Visio L2/L3 diagrams, rack elevations, and data flow schematics
  • Hardware asset inventory with lifecycle and EOL status
  • Monitoring configuration across SolarWinds, PRTG, or SNMP
  • Ticketing pipeline integration (Remedy, ServiceNow, Jira)
  • Operational runbooks for the most common scenarios

When You Need This

  • Inherited an undocumented or legacy network environment
  • Audit requires current and accurate network documentation
  • Internal team lacks bandwidth for sustained Tier-2/3 coverage
  • Hardware lifecycle is unclear and EOL exposure is mounting
  • Major project requires a clean operational baseline first
