MasterTech If It Helped Me, It Can Help Somebody Else
The story behind MasterTech MultiMedia — and why I handed my tools to a stranger.
A while back I met a guy online. He was walking a road I know well: real skills, hard work, and a feed full of people telling him AI was coming for everything he built with his hands. He was on the fence about the whole thing. Honestly? So was half my crew.
I didn't give him a speech. I showed him what I've been doing, and how I did it. Then I told him: take the tools. Use them. Tell me what's missing.
Twenty-four years of real-world work
I started in the fire department at 16. Left school, lived at the station, got my GED at sixteen, and became — as far as they'd seen — the youngest firefighter they'd ever certified. Fifteen years of fire and EMT after that. Then twelve years in the electrical trade: residential, commercial, industrial — working foreman, lead, crew boss. Between all that: satellite, internet, phone installs, factory work, HVAC, plumbing, refrigeration. A book of certifications from a few states and the government to keep score.
Today I write the documents and checklists I wish I'd had on the job, and I sat for my master electrician exam on September 15th.
Here's the thing nobody put on my report card in school: I've been a problem solver since I was sixteen. A is the problem. B is the endpoint. You figure out the in-between. Math class hated me and I hated it back — I'm a hands-on learner and the school wasn't built for hands. But every job site since taught the same lesson in a different uniform: when it's on you, the job has to work the first time.
What a weekend does
Last weekend started as a joke conversation. By Monday morning it was a working app and a server.
GenTech Helper — the offline document and day tool I always wished I had. Electrical calcs, generator fault codes and pinouts right on the tablet, checksheets, estimates, invoices, job logs, route maps. Built offline-first, because people who work away from a desk know: signal is a rumor. Tablet-first, because keyboards don't survive real work. If it doesn't hold up, it doesn't ship.
WV Master 50 — a study app I built to prep for my own master's exam. 210 questions matching the real West Virginia format, a fresh 50 every day, missed-question drills, a 15-day plan that teaches strategy instead of flashcards. The teacher I wish I'd had at 16.
On Hand — the money app that keeps my LLC and my household honest. Bills, paydays, snowball, buffer. Personal by design — my data lives on my device, not someone's cloud.
None of these came from a computer science degree. I'm not a career developer. I'm a fixer with a new wrench: me and my AI, a licensed voice model in the shop now, figuring out A→B at 2am.
So why give it away?
Because that's how the trades are supposed to work. Somebody who's been in the failure hands the next guy the map so his trip is shorter than yours. An apprentice doesn't get told "figure it out like I did" — he gets the trick, the shortcut, the warning about the breaker that bites.
We call it full circle at MasterTech: if we're not teaching the younger generation, what are we doing?
The kid who hates school but loves fixing things is not less than. He's just early. I'm proof — it took me twenty-four years to find the classroom that fit, and it turned out to be every job site in three states.
So yeah. I gave my tools to a skeptic. I'd give them to the next one too. And if your work happens away from a desk, the same practical tools that worked for me are ready for you.
Bring your paperwork problems to me. We'll sort them out together.
