AI Architect
An AI architect for AI that runs in production. Evaluated, cost-controlled, inside your permissions.
AI features inside your product, agents that run a business process end to end, and the evals and controls that keep them predictable once they are live. Monthly as a service, or on demand.

Where you are
Sound familiar? This is when an AI architect pays off.
- An AI feature that works in a demo and has to hold in production.
- A process that runs on people copying data between tools.
- A team choosing models and frameworks, and deciding where AI belongs at all.
- An agent that needs approvals and an audit trail before anyone trusts it.
What I own
AI features
Where AI creates real value in the product, built on Claude or OpenAI.
Agent systems
Specialised agents sharing one task, each inside a permission boundary you control.
A person in the loop
Whenever an agent's action departs from plan, a person decides, and every decision is logged.
Search over your data
Embeddings and vector search in PostgreSQL, tuned against real queries.
Evals
Golden datasets and regression evals for every prompt and model version.
Cost and latency
Budgets per feature, tracked in production, with alerts before they are exceeded.
Who you work with
Fractional CTO and product lead, Vienna
I design and run AI agents in production, from multi-agent systems to back-office flows, and I build my own agent products. Before AI, I spent 25 years in software architecture.
“Kristian is certainly one of the top picks in his field.”
AI in production is an architecture decision. Evals, permissions and cost come first.

One person, three roles
One person. The roles a product needs.
Product, technology and AI decisions sit with one person, so they never contradict each other. Most engagements combine two of the roles, or deliver one of the outcomes.

Enterprise AI agents
Every decision has an owner
Multi-agent workflows across your business, with human review where it matters.
AI agent evaluation
