An application built largely with AI needed to actually run somewhere: two environments, one for the team and one the client could look at, on Windows infrastructure nobody wanted to administer.
Set up and now manage the server and IIS. Reviewed the code, fixed a session cookie that would have failed silently once the app was embedded in another site, and flagged that the only thing standing between it and a CSRF hole was a cookie setting. Then a GitHub Actions pipeline running against a runner on the box itself: merge to main deploys the team environment automatically, while the client-facing one stays a deliberate manual step.
They push code and it deploys. The client environment only changes when somebody decides it should. I also traced a database that kept dying mid-deploy to the box running out of memory.
Remap were pitching for a piece of work, and the last stage of the pitch was showing a working prototype. I put the proposal document up first, then the two environments behind it: one for the team to build in, and one behind a login for the prospective client to look at. Set up across about two weeks at the end of July.
