-   "This fast-paced session of attendee demos will be a showcase of tools and practices that are making a real difference for Clojure developers today. You will see editor tools, REPL integration, connections to external systems, managing agents, and more! All experience levels are welcome. Expand the horizon of what you can do with AI and Clojure and bring those ideas back to your own projects.\r\nThe format will consist of a series of short demos (10 minutes each), culminating in a speaker panel Q&A with the audience. Due to the rapid pace of the AI development scene, demos will be proposed and chosen by the attendees a few weeks before the event.\n\n## Eric Dallo\n\nSoftware Engineer at Nubank, Emacs fanatic, NixOS enthusiast, and maintainer of some open-source projects like clojure-lsp, emacs-lsp, clj-easy and others, focusing on the developer experience.\r\n",
