Representative project patterns
These examples summarize common engagement shapes and outcomes. Details are anonymized; the engineering problems are real.
Large-Scale Data Center Fabric Migration
The Challenge
A global enterprise needed to move hundreds of network devices onto a Cisco ACI fabric without disrupting business operations. A purely manual migration would span multiple years with elevated configuration risk.
Stack: Cisco ACI, Nexus 9K, VXLAN BGP EVPN, Python, Ansible
Our Approach
- Inventoried existing configs, standards, and operational runbooks into a single source of truth
- Staged migration waves with lab validation and automated config checks before each cutover
- Documented rollback steps and maintenance-window playbooks tested in simulation
- Engineering leads on-site for critical windows with direct escalation paths
Outcomes
Enterprise Firewall Policy Rationalization
The Challenge
A multinational organization managed thousands of firewall rules in Palo Alto Panorama. Annual compliance reviews took months of manual analysis, and overlapping rules created security gaps and performance drag.
Stack: Palo Alto Panorama, GlobalProtect, Python API integration
Our Approach
- Automated exports and analysis across device groups and templates
- Identified shadowed, redundant, and conflicting rules with engineer review
- Prioritized remediation batches aligned to change windows and app owner sign-off
- Established ongoing hygiene checks instead of once-a-year fire drills
Outcomes
Hybrid Multi-Cloud Network Consistency
The Challenge
An enterprise with many data centers and workloads in AWS, Azure, and GCP struggled to apply consistent network policy. Manual changes took weeks and often diverged between teams.
Stack: AWS Transit Gateway, Azure Virtual WAN, GCP Cloud Interconnect, SD-WAN, Ansible
Our Approach
- Defined a single policy model mapped to each cloud’s native constructs
- Built repeatable deployment pipelines with peer review and automated diffs
- Standardized routing between on-prem hubs and cloud transit services
- Published topology and ownership diagrams for operations and security teams
Outcomes
ISP Circuit Provisioning Workflow
The Challenge
A regional ISP provisioned customer circuits manually—often two days per order with a high rework rate that drove truck rolls and customer complaints.
Stack: ServiceNow API, Cisco IOS-XR/IOS-XE, Python, Ansible
Our Approach
- Integrated ticketing data with standardized device templates
- Generated configurations from validated parameter sets with engineer approval gates
- Automated pre- and post-change connectivity tests before closing tickets
- Documented exception handling for non-standard sites
Outcomes
Wireless & IoT Segmentation
The Challenge
A large campus saw unmanaged IoT on wireless create security exposure. Guest, corporate, and device traffic needed isolation without cumbersome login flows for every device class.
Stack: Cisco Catalyst Wireless, Aruba Mobility Controllers, ClearPass, Cisco ISE
Our Approach
- Deployed Wi-Fi 6/6E with controller policies tuned per SSID and role
- Used MPSK and certificate-based options where appropriate for IoT classes
- Integrated ClearPass / ISE for dynamic VLAN and policy assignment
- Micro-segmentation to keep sensors and cameras off corporate application VLANs
Outcomes
What we optimize for
Different stakeholders care about different metrics; these engagements usually balance all three.
For leadership
- 01. Predictable delivery timelines
- 02. Lower operational toil over time
- 03. Reduced change-related risk
- 04. Clear documentation for audits
For engineering teams
- 01. Fewer repetitive manual changes
- 02. Designs that match how you operate
- 03. Tested automation you can maintain
- 04. Knowledge transfer, not dependency
