Yes , for the past 40 years. And CTO/co-founder.

> Do you write code for yourself or for this business?

I have been writing DSL, code generators and other tooling for the past around 20 years for this company. Before that I did the same thing for educational software (also my company).

> Who determined and what criteria define who “cannot be a client facing consultant”?

They did; some people just don't like sitting with clients noting down very dry formulae and business rules.

> What is an “in house builder”?

Our in-house tooling which uses AI to create the software.

> What were these “fulltime devs” that you said “you don’t need anymore” doing before these llms?

Building LoB apps, bugifxing, maintaining, translating Excel or business rules to (Java) code.

> Do your customers know you swapped from human workers to llms? Are they comfortable with this transition?

Yes, they like it; faster (sometimes immediate results) and easier to track; no black box; just people sitting next to you.

> How did this change result in “much higher profit margins”?

Very high fees for these consultants but now they do 'all the work'; in total they make more hours than they did before, however much less than they did as programmers. But the fees are such a multiply that the end result is larger profits.

> When you say “with less people” did you just give multiple peoples’ workloads to a single dev or did the devs you retained ask for more work?

Yes, 1 consultant now does that work and can manage more.

> What do you use an llm for in the ERP space?

Feed it specs which get translated to software. This is not the type of 'he mate, get me a logistics system in german'; the specs are detailed and in the technical format we also use to write code ourselves the past 20+ years.

> Why would clients use you if they could just use the llm?

See above, we have a lot of know-how and code built in. That's why we cannot really sell this product either as no-one will get useful stuff out of it without training.
