9:45 AM | Bending Rails conventions at scale - Chris Bisnett (Huntress) At Huntress's scale, some Rails conventions bend. This talk covers where we've held the line, where we've broken from it, and how we decide which is which.

1:30 PM | Removing 500+ foreign keys at scale -  Andrew Markle (Fullscript)

How Fullscript dropped over 500 foreign key constraints from a production MySQL database to eliminate the metadata locks causing recurring migration downtime, and moved referential integrity into the application layer instead.

2:30 PM | Agents on Rails: Quick Report - Irina Nazarova & Vladimir Dementyev (Evil Martians) The Rails Foundation commissioned Evil Martians to build and run Agents on Rails, an ongoing benchmark study to test how well agents produce Rails code. They’ll present a quick overview of their findings, and how you can help.

2:45 PM | Replacing an enterprise vendor with AI - Freedom Dumlao (Vestmark) Thanks to Claude Code, in a couple of months we replaced a clunky expensive legacy vendor with a highly scalable Rails app which can optimize tens of thousands of portfolio accounts in minutes. We did this before we got hit with a renewal, and now we sell our replacement as an additional revenue stream.

3:45 PM | Panel - When code is no longer the bottleneck. David Henner (Zendesk), Tim Labeeuw (Perry Street Software), Ryan Sherlock (Fin), facilitated by Cameron Woloshyn (Shopify) AI is dramatically increasing the amount of code teams can produce. But code generation is only one part of software delivery. What have teams had to change - in planning, architecture, review, testing, shipping, and collaboration - to keep pace?
