Available to design and build new agentic products

Marvin.

I build agentic systems that do real work without losing control.

If you're building an AI-native product or a new agentic business, this is the work I do end to end: the data model that becomes the source of truth, the boundaries that make agents safe to trust, and the product people actually use. The case studies below show how, decision by decision.

Working principles

How I work.

01

Your problem first, my stack second

Before writing code I get inside the actual operation: where time dies, where money leaks, what a win looks like in numbers. The architecture follows from that, not the other way around.

02

Working software, early

You see something real running in the first weeks, then we iterate on what actual usage teaches. Roadmaps and decks don't survive contact with the operation. Deployed software does.

03

No AI theater

If a deterministic rule beats a model, you get the rule. Agents earn autonomy in small, reversible steps behind validation and audit. You're paying for outcomes, not for a demo.

04

Built to hand over

A feature is done when your team can run it without me: observable, debuggable, documented. I measure success by what keeps working after I leave.
