About
The person you call when something breaks.
At the Navy's boot camp in Great Lakes, my crew kept 42 buildings running on 240 acres and handled 2,461 repair requests. When something broke after hours, the phone rang and we went. Two rules came out of that job and never left: fix it right the first time, and always pick up.
Computers have been the other constant in my life since I was about 13. Over the last year I built Shprd, a full family app, with a web version, an Android version, payments, and an AI assistant. I build with a crew of AI coding agents that I direct and review, which is how one person can ship work that used to take a team.
Main & Maple is where those two halves meet. Local businesses need websites that bring in calls and phones that get answered. Families need someone patient to fix the Wi-Fi and spot the scam text. I can do both, and I live close enough to show up.
When I'm not fixing something, I'm with my family, at church, or behind a camera.

How I work
Price first
You'll know what it costs before I start. If something changes, you hear about it before it's billed.
Plain English
You should understand what you pay for. I explain things without jargon, and I write it down.
Show the work
Every job ends with a short note: what I did, what it cost, and what to do if it acts up.
Your stuff is yours
Your domain, accounts, photos, and data stay in your name. I never hold a business hostage.
Honest about AI
It's a tool, not magic. If you don't need it, I'll say so.
