Multi‑Site Network Core
Designing and operating Cisco‑based WAN/LAN across 40+ distributed enterprise locations with BGP, OSPF, MPLS, and QoS.
15+ Years
Rebuilding networks, security, and platforms in production
Building systems & networks into secure, automated, cloud‑ready platforms.
Lead Network Engineer with deep experience in Cisco Nexus/IOS, ASA, AWS networking, and security frameworks (CIS Hardening, DISA STIG). I design and migrate multi‑site networks, enforce compliance, and use Python/Ansible and AI‑driven tooling to keep environments resilient.
Systems & Network Engineering
End‑to‑end enterprise systems and network engineering.
From core routing and Nexus datacenter fabrics to Juniper Mist wireless and virtualization, I treat the network and systems stack as one integrated platform—designed for uptime, security, and scale.
Wireless & Access
RF‑driven Wi‑Fi design with secure access, RADIUS, WPA2/WPA3, and predictive surveys using Ekahau.
Systems & Virtualization
Integrating Windows Server, Linux (Red Hat, Ubuntu), VMware, and Hyper‑V into resilient network designs.
Observability & Uptime
Designing monitoring to hit 99.9%+ SLAs with fast troubleshooting, clear runbooks, and proactive alerting.
DevOps & Cloud Platforms
Building cloud-native infrastructure with Kubernetes, Terraform, and CI/CD pipelines for automated deployments.
Automation & Scripting
Developing network automation with Python (Netmiko, Paramiko, Requests), Ansible, and REST APIs for config management.
Cloud & Cyber Security
Senior cloud infrastructure security with expertise in Kubernetes hardening, AWS security architecture, and cloud-native threat mitigation.
Cloud & Security Rebuilders
Rebuilding networks around cloud and security first.
I help teams refactor legacy architectures into cloud‑aware, compliance‑aligned designs with AWS VPCs, Direct Connect, VPNs, and hardened Cisco infrastructure following CIS and DISA STIG standards.
Cloud‑Connected Enterprise Network
Designed multi‑site Cisco infrastructure integrated with AWS VPCs, Direct Connect, and Transit Gateway, enforcing segmentation and secure hybrid connectivity across campus and cloud.
CIS & DISA STIG Hardening Program
Led CIS Hardening and DISA STIG standards implementation for Cisco Nexus, IOS, and ASA platforms, achieving 100% compliance validation with repeatable checklists, audits, and remediation workflows.
Secure VPN & Access Control Architecture
Built IPSec/SSL VPN designs, RBAC policies, and segmented access to enforce least privilege and Zero Trust‑aligned architectures across distributed sites.
Multi‑Phase Network Migration
Executed zero‑downtime network migrations with rigorous change control, testing, and vendor coordination across multi‑phase data center modernization efforts.
Enterprise Wireless Security Rollout
Deployed enterprise‑grade wireless with WPA2/WPA3, RADIUS authentication, and predictive RF surveys supporting seamless roaming and mobility across 40+ sites.
Automated Compliance Validation
Developed automated network compliance validation aligned with CIS Hardening and DISA STIG requirements, reducing drift and human error through infrastructure‑as‑code.
Kubernetes & CI/CD Platform
Designed and deployed Kubernetes-based container orchestration platform with Terraform IaC and CI/CD pipelines, enabling automated application deployments with Git-based workflows.
Python Network Automation Suite
Built comprehensive Python automation suite using Netmiko, Paramiko, and Requests libraries for device configuration, API integrations, and network state validation across multi-vendor environments.
Cloud Infrastructure Security Program
Designed and implemented senior-level cloud security architectures including Kubernetes cluster hardening, AWS security controls, IAM policies, and Cloud Security Alliance best practices for enterprise workloads.
Architect Blueprints & AI/ML Networks
Blueprints for networks that use automation and AI to stay healthy.
I capture architectures as living blueprints: from Python/Ansible‑driven config generation to AI‑assisted troubleshooting with Mist Marvis and intelligent monitoring—reducing MTTR and provisioning time.
Infrastructure‑as‑Code Blueprint
Automated configuration generation for Cisco and Juniper using Python (Netmiko, Paramiko, Requests), Ansible, Terraform, and CI/CD pipelines, creating reusable blueprints for VLANs, routing, and firewall policies with Git version control.
AI‑Assisted Wireless & Network Operations
Combined Mist Marvis AI‑driven troubleshooting with SolarWinds and custom Python tooling to cut MTTR by 60%, using intelligent insights and automated checks across 40+ sites.
Network Automation Factory
Built reusable automation runbooks using Python, Ansible, Bash, and Git that standardize provisioning and compliance validation, reducing device deployment time by 70% across Cisco Nexus, IOS, and ASA environments.
Architecture Blueprint Components
Network Topology Diagrams
Logical and physical network diagrams with VLAN segmentation, routing protocols, and security zones.
Security Architecture
Firewall policies, VPN tunnels, RBAC models, and Zero Trust segmentation aligned with CIS/DISA STIG.
Cloud Integration Design
AWS VPC architecture, Direct Connect, Transit Gateway, and hybrid connectivity blueprints.
Automation Workflows
Python (Netmiko, Paramiko, Requests), Ansible, Terraform, Git, Bash, REST APIs, Jinja2 templates, and CI/CD pipelines for config management.
AI/ML Network Operations
Mist Marvis AI troubleshooting, predictive analytics, and intelligent alerting for proactive ops.
Compliance & Audit Frameworks
CIS Hardening checklists, DISA STIG validation, and audit‑ready documentation for federal standards.
Cloud & Cyber Security
Kubernetes Security (CKS), AWS Security Specialty, CCSK frameworks, and senior cloud infrastructure protection.
