THE PERSON / THE EXPERIENCE
A career across systems, shop floors, products, and people.
Jack of All Trades,
Master of None.
THE SHORT VERSION
I bring 18+ years of customer service and support across multiple industries. I’ve been a voice of the customer champion across that work, including ten years in commercial fabrication and quality control and eight years in professional 3D printing. 3D printing has also been a hobby and passion for 13 years, and I’ve spent 26+ years moderating and administering online communities.
The handle came from peers who found I usually knew something about the thing they needed help with. After a few career changes, it stuck. So did the curiosity.
Today that shows up in printer firmware, AI-assisted development, code review, and game modding. With 5,000 hours in Factorio, I’ve spent plenty of time on the player’s side of the mods I work on.
Millennial. Lifelong troubleshooter. The midlife crisis will have to take a number.
The work behind the skill set.
Customer service and support have run through most of my career. As a voice of the customer champion, I work to understand the problem and make sure customer needs and feedback shape decisions.

A background in sheet metal and CNC machining, quality control, and production coordination. The work also included expediting, logistics, and contract negotiations: the practical details that keep production moving.

My professional work spans testing and validation, R&D, product planning, program management, and customer support. Beyond the job, 3D printing has been a hobby and passion for 13 years.

I built inventory management and production tracking systems, alongside blogs and CMS tools, by hand in HTML and PHP. My early work also included computer systems administration.

More than 26 years moderating and administering communities across forums, IRC, and Discord. That experience covers both the people in a community and the platforms they rely on.

Current work includes printer firmware, provider compatibility tools, code review, and Factorio mods. I use AI to help develop and investigate, then check the output against the problem it’s supposed to solve.

High standards. Low tolerance for bullshit.
“We’ve always done it that way” isn’t an explanation. I want to understand the constraints, then decide whether the process still makes sense.
AI is useful when it helps solve a problem. I review, test, and question its output just as I would any other contribution.
Being a voice of the customer champion means understanding what people are trying to do, then making sure their feedback influences both the answer and the product.
