About this Gig
Stop manually checking dozens of commands after every network change
I'm a Cisco network engineer with 8+ years in enterprise routing, switching, and data center environments now specializing in Python-based network test automation with Cisco pyATS and Genie.
I'll build you a custom pre/post-change validation script that automatically:
- Captures a "golden" baseline snapshot of your device state (interfaces, routing tables, BGP/OSPF neighbors, CPU/memory, etc.)
- Re-runs the same checks after your change
- Diffs the results and flags anything that didn't come back clean
- Delivers a clear pass/fail report you can attach to your change ticket
This is built on the same framework Cisco itself uses internally to test millions of changes a month so you're getting an enterprise-grade validation process, not a one-off script.
Works with Cisco IOS-XE, NX-OS, IOS-XR, and ASA. Multi-vendor support (Arista, Juniper) available on request.
Message me before ordering so we can scope your exact device types and commands every network is different, and I want to get this right the first time.

FAQ
Do I need to give you access to my live production network?
No — I can build and test against sample "show" command outputs you provide, or a lab/testbed environment. Production access is optional and only if you're comfortable.
What if pyATS/Genie doesn't have a built-in parser for one of my commands?
I can write a custom parser as part of Premium, or as an add-on for Standard/Basic.
Can this run automatically, not just on-demand?
Yes — ask about the CI/CD add-on (GitHub Actions) to trigger runs automatically on a schedule or on config push
Do you sign NDAs?
Yes, happy to sign a standard NDA before receiving any device details.
What do I need to have ready before ordering?
Device list, OS versions, and (ideally) sample CLI output or lab access — the more detail up front, the faster delivery.
