I’ve seen systems and people break. Now I write about how we rebuild.

For more than two decades, I built, fixed, and watched it all fail again.
The Apache Software Foundation became my second office, and my teams were spread across the world. After Log4shell, I learned once again how fragile our the codebases of our lives can be.
I'd seen before how code depends on trust, empathy, and care. Now it’s been engraved in my mind.

Logging Off grew out of those lessons.

I was named a Java Champion, a recognition for my technical and community contributions. As VP of Data Privacy for the Apache Software Foundation, I guide open source governance and ethics.
I wrote multiple books, The Zen Programmer in 2014 and Java Logging with Log4j in 2025, currently in Manning's MEAP program.

I run my own company, Grobmeier Solutions GmbH, and focus on sustainable software and security. For almost a decade, I've trained young developers on Java, Spring, and related topics. As a speaker, I was invited internationally and am very grateful for that.

To me, technology is more than just code.

It's about the people who maintain it. When we talk about resilient systems, we often forget resilient humans. With the arrival of AI coding systems, the human factor is even more overlooked, yet remains essential.

Logging Off is where I write about that tension between staying sane and ethical, while creating things that outlive us. It’s not a retreat from technology. It’s an attempt to rebuild our relationship with it.

Have you felt the same weight?

If you know the burden of open source, leadership, or even burnout—you'll find echoes here.
If you're thinking about the future and AI, cybersecurity, or developers' responsibilities, you'll find more questions here, but no slogans.

I decided to think, write, and build in public.
Quiet.
But with intent.

I invite you to join me.
