Proof, not promises.
Here are things I have built. Most cross more than one service, so each one is tagged with every service it shows.
Foundation repair
LightScan
An iPhone app for a foundation repair company. The estimator walks through a house and the phone's laser scanner draws the floor plan with every wall length, plus a heat map of where the floor sags or heaves. The app turns the scan into a report for the customer, with the foundation outline, a floor elevation map, and rainfall and soil for the address, and into a model you can 3D print. The first working version was on their phone a day after they described the problem. See the printed model
FieldADE
An iPhone app that reaches the AI assistants on my Mac from anywhere, over a private network. A chat app on your phone starts every answer from zero. These assistants run where my records live, next to my files, email, notes, and the vault that holds what I know about each job, and a knowledge assistant keeps all of it indexed. So from the truck I can ask what we quoted a customer last spring and get the quote, or ask for the follow-up and get it drafted from that thread. The records stay on the Mac; the phone only reaches them. Each chat runs in a folder, replies appear as they are written, and photos go along with a message. Before an assistant edits a file or runs a command, the phone buzzes and asks me to allow or deny it. I can change the app from the app: an assistant edits the code, checks it, and installs the new version on the phone. See how it connects
HomeADE
The Mac app FieldADE talks to. It runs the assistants on your Mac, takes each message from your phone, and sends the answers back. It opens a window with the same screens as the phone, so you can pick up any chat at the Mac where you left it on the phone, and a menu bar panel shows that it is running and pairs a new phone. It installs like any other app: no terminal, no setup scripts. Your files, email, and notes stay on the Mac; the phone only reaches them. See how it connects

Or install with Homebrew:
brew install --cask jtembry/homeade/homeadeKingdom Guide
An iPhone app that plans a day at Magic Kingdom. It puts the rides a family picks in walking order, estimates when they will reach each one, and shows the posted waits. For families who use the Disability Access Service, it says which ride to book next and reminds them when the return time comes up. The next stop sits on the lock screen, the map is drawn from open map data, and everyone on the trip sees the same plan. It began as a web page for our own trip and is headed for the App Store. About the app
Small business
Flourish Financial Group
A financial counselor's site, live about a month after the first conversation. It is static and fast, costs $0 a month to host, and sits in her own GitHub account with a written guide, so she runs it herself.
3D printing
Featured prints
I design and print custom pieces for marketing and promotion: business cards, card holders, signs, and giveaways with your name on them. Each one starts as a short conversation and comes off my own printer. Visit the 3D shop
