For CEOs
Your IT budget keeps growing. And nothing gets better.
You can't evaluate what you're paying for. You hate open-ended consultant billing. Every quarter the IT budget grows and the problems stay.

You don't need to understand the shoe to know it's pinching. You just need someone who can tell you why — and fix it without selling you a new pair every quarter.
The number was a legal liability. Then I left.
HORNBACH had 28-hour batch jobs failing daily across 169 stores in 9 countries. I rebuilt the pipeline from scratch — 28 hours to real-time. Cloud savings so large the number was legally prohibited from being disclosed. 6 engineers freed. Then I moved on.
Proof: HORNBACH
The immune response.
I've been legally threatened for revealing cost savings.
I've been fired for finding a compliance crisis the principal engineer missed.
I've been told not to fix another team's broken code — because fixing it would embarrass the person who chose the vendor.
Not because I was wrong. Because I was right, and being right made people uncomfortable.
If your organization shoots the messenger, we're not a fit. If you're the person who HIRES the messenger because you need the truth — call me.
If I do my job right,you'll fire me in three months.
I don't sell retainers. I don't build dependency. I find the root cause, fix it with your team, and leave. That's the design — not the accident.

Lars consistently demonstrated a strong bias for action — he didn't wait around but took the initiative to push things forward. His decisiveness made a real difference to the pace and outcome of our work together."
