A named principal engineer does the work.
You are not sold a partner and delivered a junior. The person in the discovery call is the person writing the code.
OperiProof's principal engineer has worked in networking since 1992 — including seventeen years in carrier and cable-operator network operations, starting with a regional ISP in 1997. That is the environment these buyers run in, at a scale most of them aspire to.
A regional operator's engineering leadership does not have to be persuaded that carrier-grade operations discipline is real. They are trying to reach it with a fraction of the staff. That is the work.
Carrier operations depth, plus software engineering discipline.
Software skill without service-provider operations depth.
Operations depth without CI and test discipline.
Both. Version control, continuous integration, automated testing, reproducible builds and rollback, applied to a production carrier network.
Method, not claims.
Saying what a technique cannot prove builds more credibility than claiming it proves everything. Offline analysis finds reachability faults before a change ships; it does not replace live testing. Emulation reproduces a topology; it does not reproduce your traffic. We will tell you which is which.
