CLI again?? Every time you adopt a trend you rebuild your architecture. In this talk, Dan Farrelly, Inngest cofounder and CTO, is not going to tell you what comes next. He's going to show you how to build so it doesn't matter. He'll cover the core primitives that show up in every production agent, how bringing decisions closer to code provides more stack flexibility, and why the right execution layer unlocks faster iteration. ### Dan Farrelly CTO and Co-founder · Inngest [LinkedIn](https://www.linkedin.com/in/djfarrelly) Dan Farrelly is CTO and co-founder of Inngest, a platform for durable serverless functions, workflows and agent orchestration.
