From Design to Deployment: Engineering solutions that move organizations forward.

Migration to Webex Cloud Calling

Journey with a K-12 ISD to migrate from Cisco UC on-premise to Webex Cloud Calling

This project involved planning and executing a full migration from a legacy Cisco Unified Communications Manager (CUCM) deployment to Webex Cloud Calling for a large K-12 independent school district. The effort required a thorough audit of the existing on-premise environment — including hunt groups, auto attendants, voicemail, and analog endpoints — followed by a phased cutover strategy that minimized disruption to campus operations during the school year. The result was a modern, cloud-managed calling platform with simplified administration, improved reliability, and reduced infrastructure overhead.

Key areas of focus:

CUCM-to-Webex Cloud Calling migration planning and dial plan translation
Phased site-by-site cutover across multiple campuses
Integration with existing network infrastructure and QoS policies
End-user training and change management coordination

Cisco Catalyst Management with Meraki

Modern network management with a local City in the State of Texas

This engagement brought centralized, cloud-managed visibility to a municipal network by deploying Cisco's Catalyst management through the Meraki dashboard. The project addressed the City's need for a simplified operations model across distributed sites while retaining the performance and feature depth of Catalyst switching and routing infrastructure. The deployment unified monitoring, configuration management, and firmware lifecycle into a single pane of glass, enabling a lean IT team to manage their environment more efficiently.

Key areas of focus:

Onboarding Catalyst switches and access points into the Meraki cloud dashboard
Network topology assessment and site-level segmentation design
Centralized policy management, alerting, and firmware scheduling
Operational training for City IT staff on the Meraki management platform

Microsoft PKI and Cisco ISE 802.1x Authentication

Leverage certificate-based authentication to authenticate clients to an enterprise network

This project stood up a certificate-based 802.1x authentication framework using Microsoft Active Directory Certificate Services (AD CS) and Cisco Identity Services Engine (ISE). The goal was to move the organization away from credential-based or MAC-bypass network access toward a more secure, scalable posture. The solution involved deploying an internal PKI hierarchy, configuring certificate auto-enrollment via Group Policy, and building ISE authentication and authorization policies that dynamically assigned VLANs and access levels based on device identity and compliance status.

Key areas of focus:

Microsoft AD CS PKI design — root and issuing CA deployment
Certificate templates and auto-enrollment via Group Policy
Cisco ISE policy sets for wired and wireless 802.1x authentication
Dynamic VLAN assignment and posture-based access control

Pure Storage for Enterprise Applications

Use hyperfast flash storage to enhance the performance of SQL Servers, NVR Systems, and more

This project replaced legacy spinning-disk storage with Pure Storage FlashArray to deliver consistent, low-latency I/O for performance-sensitive enterprise workloads. The deployment targeted SQL Server databases, network video recording (NVR) systems, and other I/O-intensive applications that had outgrown the capabilities of traditional SAN infrastructure. The result was a measurable improvement in application response times, simplified storage administration through Pure's management interface, and a reduction in physical rack footprint and power consumption.

Key areas of focus:

Pure Storage FlashArray deployment and integration with existing SAN fabric
SQL Server and NVR workload migration with minimal downtime
Performance benchmarking and validation against legacy storage baselines
Ongoing management via Pure1 and snapshot-based data protection
