Senior engineers you'll actually work with.

Supported a full refresh of OJP's enterprise firewall environment, migrating from legacy appliances to a modern Cisco FTD/FMC architecture. Handled discovery, rulebase analysis, configuration development, and validation for a zero-downtime transition — translating ACLs, NAT, routing, IPsec tunnels, and objects, rationalizing redundant policies from ASA logs, and building optimized FTD configurations with port channels, sub-interfaces, and segmented security zones.

Designed and implemented a comprehensive enterprise security architecture integrating Cisco ISE, SNA, and SIEM for unified visibility and policy enforcement. Deployed Cisco FTD/FMC firewalls and advanced authentication frameworks (Azure MFA, Active Directory), and led efforts to centralize logging, automate alerting, and improve incident response with custom SIEM dashboards and correlation rules.

Provides network engineering support for DEA and Howard County, assisting with complex routing and failover analysis. Helped identify and correct a design gap that prevented automatic Internet failover, implementing improved route tracking and resiliency to ensure uninterrupted connectivity for critical public safety services.

Engineers migrations to modernize and secure enterprise networks. Designed and implemented a Cisco ISE deployment providing TACACS authentication, authored design standards and policies, optimized multi-classification network consolidation onto an MPLS backbone, and leveraged Cisco DNA Center for device inventory and lifecycle management.

Deployed Cisco WAN routers and switches under DISA STIG compliance. Developed QoS for voice/video/data, automated AAA configs via DNAC, upgraded network code using SWIM, and redesigned inter-network traffic using VRF-Lite and Cisco FTD firewalls. Executed MPLS and MP-BGP migrations and mentored junior engineers on enterprise routing and multicast.

Supported tactical and enterprise-grade communications networks for U.S. Army Special Operations Command. Installed, configured, and maintained Cisco infrastructure in classified environments, contributing to secure, mission-critical connectivity worldwide.

Led the DART implementation effort, a three-site deployment of a full Meraki network stack including firewalls; core, distribution, and access switching; and wireless APs. As primary technical lead, developed the network design, configured the environment, guided implementation, and provided knowledge transfer and staff training.

Led global modernization of LAN, WLAN, and firewall environments across headquarters, distribution centers, and remote offices. Engineered and deployed wireless solutions, performing design, validation, and troubleshooting with advanced survey tools to improve coverage and reliability.

Supported global LAN/WLAN design and modernization across corporate, manufacturing, research, and remote-office environments. Led migration of autonomous wireless to a controller-based architecture enabling ClearPass NAC adoption, and designed wireless for 3M's multi-floor headquarters and research facility — performing active surveys and RF planning for 100+ Cisco APs across highly variable, heavily shielded environments.

Provided troubleshooting and technical support for the Meraki product line within strict SLAs. Diagnosed complex wireless, switching, and security issues using lab replication and deep platform knowledge, gaining extensive hands-on familiarity with Meraki wireless infrastructure, Layer 2/3 switching, and security appliances.

Serves as technical lead for the Coast Guard's Cisco ISE Comply-to-Connect (C2C) deployment. Guided discovery, design, and implementation of wired 802.1X and MAB authentication, redesigned the ISE policy framework to align with Zero Trust and DoD C2C standards, and validated configurations through phased cutovers while coordinating with Coast Guard IT to ensure uninterrupted operations.

Leads network security architecture and vulnerability management. Implemented Zero Trust architecture, managed Cisco ISE for access control, and configured Palo Alto, Cisco, and Juniper firewalls. Conducted enterprise vulnerability scanning and remediation with Nessus and SCAP, hardened systems to NIST and DoD standards, and deployed BeyondTrust PAM.

Designs and maintains secure network infrastructures supporting global operations. Develops Ansible and Python automation for system patching and configuration, conducts penetration testing, and ensures DoD compliance across physical and virtualized environments including VMware NSX and cloud systems.

Managed security compliance and system hardening for multi-site infrastructure. Enforced DoD STIG requirements, administered Cisco and Juniper devices, and conducted regular vulnerability assessments, risk remediation, and disaster recovery validation.

Leads product strategy and development for Cisco SDA and Catalyst Center, owning the end-to-end product lifecycle — PRD, roadmap, features, and AI use cases. Drives platform direction for U.S. public-sector and enterprise customers and introduced AI-driven clustering for network anomaly detection and predictive analytics.

Led engineering teams designing U.S. Army enterprise networks using Catalyst 9K, Nexus 7K/5K, and Cisco ASA/FWSM firewalls. Stood up a new cloud services practice, built CSP reseller partnerships, and guided next-generation technology adoption including SDN and data center modernization.

Architected a secure hybrid-cloud environment for the firm's global cyber security practice, integrating AWS Direct Connect with private cloud and a cyber-centric monitoring model. Led proof-of-concept labs evaluating emerging cloud products against industry and customer requirements.

Led data center architecture, design, and implementation using Nexus 5K and 7K with FabricPath, supporting day-to-day operations of the Census network and mentoring Tier 1–3 engineers across architecture and operational roles.

Architected and deployed large-scale data centers (Nexus 7K/5K/2K, UCS, Catalyst 6500 with VSS) and a DMVPN small-site architecture spanning roughly 900 global sites for General Motors and GMAC, and served as MPLS backbone course instructor for major enterprise customers.
