About

A telecom call flow is a sequence diagram: one box asks a question, another answers, a third one acts on it, and the whole exchange has to complete correctly or the call drops. I've spent most of two decades reading and debugging exactly that kind of diagram — SS7 and SIP messages moving between switches and intelligent-network platforms — and I still do. An AI product built around a language model is the same diagram with different actors: a request comes in, a model classifies it, a rule decides what happens next, and a system of record gets updated. The shape didn't change. What's new is that I now design the diagram as well as keep it running.
