A 3D sports card store. The shopkeeper is modeled on me and knows it.
Chris Birk, a data & AI architect from Uptown with 15 years in the trade, reportedly cannot stop making things. Sources confirm most of them work.
CHICAGO — By day he builds data pipelines, warehouses, and AI agents for clients through his consultancy, CrossroadsCX. By night the same skills get pointed at a football tower-defense game, a 3D card shop with a shopkeeper modeled on himself, and a self-hosted agent named Crowley that works a kanban board without supervision. His code has been to Congress. It came back with notes.
“I like systems that hum along on their own,” Birk said, gesturing at a 3D printer mid-job. “And games with too much strategy. And making things that don’t strictly need to exist.”
Asked whether the projects were for work or fun, he declined to pick. The projects themselves are still on the editor’s desk, page 2, awaiting approval they will not receive.

Upload every photo from the wedding. It sorts them by face and sends each guest only the ones they're in.
A self-hosted agent that works a kanban board on its own. Occasionally opinionated.
Ask who filed for what in North Carolina. A RAG agent answers, with receipts.

New stories are filed as they’re built. The editor will find something wrong with each of them.
UPTOWN — Press and drag from the cue ball to aim; let go to shoot. Pull farther for more power. Birk, who shoots APA 9-ball on Wednesdays and 8-ball on Thursdays, is building a computer-vision system to track exactly this kind of shot (see Pool Analytics, page 2, still a spike). Early findings: the model is more consistent than he is.
Pipelines, warehouses, and AI agents for teams that need things to actually ship. Agents wired into your warehouse and CRM, with a human approving anything that matters. Everyone’s being told they need AI. Some of them are right. We’ll tell you which, then build it.
