Software that runs the real work.
I build the apps operators run their day on: work orders, purchasing, billing, ordering portals, and the AI that ties them together. Shipped to production and kept running.
How a problembecomes an app.
Every project follows the same route: a problem your team lives with, the skill that fixes it, the tools I build it with, and the app it ships as. Each dot is a real route from my work. Tap any stop to trace it.

I came to software from the operations side, so most of what I build started as a problem I sat right next to.
Invoices billed back to properties by hand. Maintenance requests lost in text messages. Purchasing spread across spreadsheets and inboxes. Each one became an app that people now use every day.
I build with modern AI tooling end to end, which lets a small studio design, ship and support what used to take a full team. You work directly with me, from the first call to the version your team runs on.
