An AI consultant who can actually build it. — Jorrit Keijzer

I help small businesses and teams put AI to work — then build the product around it. Strategy, agentic engineering, training and full-stack delivery, from one person who does both.

I find where AI saves your team real time, build it into your product or workflow, and make sure you can run it without me.

How I work

The reason to work with one person who both advises and builds: nothing gets lost in between.

Advice that ships

Strategy is only useful if it survives contact with the build. I move between both, so recommendations stay grounded in what's actually deliverable.

One point of contact

No hand-off between the person who advises and the person who builds.

Guardrails by default

Agents and automation that fail safely, visibly and recoverably.

Teams that stay fluent

The goal is a more capable team, not a more dependent one — patterns they keep using long after I'm gone.

Tell me what you're trying to do with AI — or what you suspect you could. I'll tell you honestly whether it's worth building.
