AI Engineering · Fractional CTO
I build AI products that actually ship.
I'm Timo — a hands-on engineer and former startup CTO. I take founders from raw idea to a production AI product, orchestrating AI agents to ship at the pace of a full team — then keep building alongside you. One senior person, no team to manage, no overhead.

What I do
One senior engineer who can take you from idea to shipped — and stay.
Most of my work is hands-on AI product development. The CTO experience is what makes the decisions along the way the right ones.
AI Engineering & MVPs
From prompt to product. I design and build AI features, agents, and complete MVPs — then keep making them sharper.
Ongoing Development
A senior engineer on retainer. I own features end to end and ship continuously — no team to spin up, no handoffs.
Fractional CTO
Senior technical judgment without the full-time hire. Architecture, roadmap, hiring, and investor-grade due diligence.

The premium option
Raising or scaling? Get a CTO's judgment without a CTO's salary.
I've sat in the chair — co-founder, CTO, VP of Engineering. When the stakes are architecture decisions, hiring, or a technical due diligence, you want someone who has done it before, on call.
Discuss an engagement →How I work
Small loops. Real software. You in the room.
A focused call to pin down what actually needs building — and, just as often, what doesn't.
I ship a working version fast, in tight weekly loops, with you seeing progress the whole way.
I stay on to refine, extend, and harden for production — as long as it's useful to have me.
