Questions about this work

Are these real engagements?

Yes. Each study describes work Welzin delivered, written up around the metric it was scoped to move rather than the technology used to move it.

Why are some clients unnamed?

Because not every client wants to be. Where a name is not shown, the sector and the shape of the problem are, and the engineering detail is unchanged.

Can you do this for our problem?

That depends on whether there is a number attached to it. Tell us the metric and we will say plainly whether it is a fit, including when it is not.

Want the same kind of write-up about your system?

Tell us the metric that is stuck. If we have done comparable work, we will point you at it - and if we have not, we will say that instead.
