Engineers who build fabrics, not tickets.
SpineRail is a Frisco, Texas network engineering firm. We design, build and operate VXLAN EVPN fabrics, AI datacenter networks, SD-WAN and firewall platforms on Juniper, Cisco, Arista and Palo Alto — as code, with a dry run before every change.
How we work.
Every engagement has one accountable lead, a written plan, and a repository where the design lives as code. Changes are pull requests, validated on a digital twin of your fabric before they reach production. You see the same live health portal we do.
We publish our engineer-to-sales ratio because it is the number that predicts how a project will go. Today it is 9 : 1. We update it quarterly.
Headquarters: 12800 Westridge Blvd STE 109, Frisco, TX 75035. Delivery is nationwide, remote-first, with engineers on site for cutovers, cabling and commissioning.

Seven promises.
- 01No change without a digital-twin dry run
- 02Live fabric health portal for every customer
- 03Price on demand, verification on every wave
- 04Engineer-to-sales ratio, published
- 05Senior engineer on a Sev-1 within 15 minutes
- 06Multi-vendor by design: Juniper, Cisco, Arista
- 07Every design delivered as code, repository included
How a program moves through us.
Discovery to operations, the same engineers. Every stage below has a named output you can hold in your hand — and the twin sits between design and every cutover.
Discovery
Inventory, dependencies, constraints and risk map collected from the running network. Output: inventory workbook and fixed program scope.
Assessment
Current state measured against the target: capacity, resilience, security posture. Findings ranked by risk and effort.
Design
Target architecture, translation rules and bill of materials — written into the repository you will own.
Twin validation
Candidate configuration applied to a digital twin: predicted state, routes and failures proven before any window is booked.
Build & migrate
Racks, cabling and cutovers in waves with parallel running; rollback tested and rarely used.
Verification
Pre/post checks against baselines and application tests; the next wave starts only when this one is signed off.
Handover
As-builts, runbooks, test results and the repository transferred; your team trained on the pipeline.
Operations
Live health portal, 15-minute Sev-1 response, changes through the same twin-gated path.
