# About Arne Kellmann

Arne Kellmann is an AI solution architect: the person who decides how an AI feature is actually built — what the model is allowed to do, where its context comes from, how the system fails safely, and what it costs to run once real users depend on it.

He works remotely with teams anywhere, in English or German, and brings 15+ years of software development and architecture to the design work.

Arne Kellmann designs and builds the system around an AI model — retrieval, evaluation, guardrails and cost control — for teams whose prototype already works but is not yet ready for real users, a compliance review or a monthly bill. Engagements are remote and begin with a written architecture assessment that you keep whether or not a build follows. He works worldwide, in English or German, with 15+ years of software architecture behind the AI work.

Every engagement runs in the same four stages, so you can stop after any one of them and still hold something useful.
