The Practice

Three ways I work. One outcome: your team runs it without me.

I advise before a big data or AI decision, take the reins when the work has to get done, and train the people who carry it on.

How Engagements Run

Architect. Embed. Hand over.

The same three phases govern every engagement. They scale to what you need: a plan, someone to lead the work, or a trained team.

01

Architect

Understand the current system, test the target architecture and plan, and define the outcomes it will be judged on.

02

Embed

Build alongside the team. Hire or transition the permanent lead, and put the documentation, routines, and decision rights in place.

03

Hand over

A dated handover: documentation, training, shadowing. The permanent lead is in place, and nothing depends on me.

Based in Paris, France · works internationally · onsite and remote · English & French

Next step

Have a system to build, and to hand over?

Write with the problem you are facing. I reply personally, and I will tell you if it is not a fit.
