Somewhere right now, a blood-gas analyser is telling a clinician what to do next. A hearing aid is quietly doing its job mid-conversation. An aircraft's weapon-release logic is holding to the spec it was built to. None of that happens by accident — it happens because someone tried, hard, to break it first.
That's the job. I sit at the critical intersection of humans and machines, hunting for the failure mode nobody thought of yet — across medical devices, avionics, and industrial systems.
FAQ
What does "PM-QA" mean?
My initials, plus the discipline I work in. No pretension intended — it just happened to make a good domain name.
What do you actually do?
Verification & validation. I try to find the ways a system fails before it reaches the person depending on it — medical devices, avionics, industrial software, occasionally banking systems.
Are you a developer?
No — I break other people's software, professionally. This site is one of the only things I've built myself, with a fair amount of help from Claude. See the Projects section.
Where are you based at the moment?
I live in Augsburg — though I've relocated country twice already, first to Switzerland, then to Germany. If there's a really fascinating offer from somewhere else, I'd definitely consider it.
"We have a really fascinating new role for you, are you interested?"
Well, yes, definitely — please get in touch.
Which industries do you work across?
Medical devices, avionics/defence, industrial systems, and some banking/financial software — I move quickly into new tools, standards, and domains rather than staying fixed to one.
Do you travel much then?
Yes, I have travelled a fair bit across several countries in Europe including Germany, Czechia, Denmark, Sweden, Switzerland, Poland, some of Canada and northern Australia.
What do you mean by "Entertainer"?
It's one of my hobbies, perhaps more of a lifestyle, helps me to meet people, to understand, to entertain, to make them smile & laugh, to sympathise, to appreciate them, to encourage them.
About / My Story
A few of the moments this work has actually mattered — told straight, weaknesses included.
Airbus Tornado programme — avionics, DO-178C
A stretch on the Tornado programme, working close to weapon-release systems and the radar-linked communications behind them — the kind of environment where "probably fine" isn't a phrase anyone uses. Some of it I can't get into here, but it's some of the most exacting verification work I've done, inside a DO-178C-governed world where every line has to trace back to why it's there.
Roche cobas b 123 — blood-gas analyser
The cobas b 123 is a point-of-care blood-gas and electrolyte analyser used in emergency rooms and critical care settings. My role covered system-level test planning and safety verification work under ISO 14971 risk-control requirements.
Sonova myPhonak — hearing aid platform
myPhonak is Sonova's connected hearing aid platform, pairing the device with a companion app. My role covered testing across that platform, including safety-relevant issue identification within a regulated, audiology-governed development process.
Skills & tools
Projects
pm-qa.org — built with Claude
This entire site — domain research, DNS setup, content, and the illustrations above — was built working alongside Claude. I'm not a developer; I'm someone who tests other people's software for a living. This was a genuine hands-on look at what AI-assisted building actually looks like end to end: research, drafting, design decisions, and the fiddly real-world bits like DNS propagation and licensing checks on images.
It's also a small, honest data point for my own field: AI-assisted testing and tooling is listed as active, current learning in my skills above — this site is one concrete example of working that way in practice, not just a line on a list.
