He explores alternatives to heavy JavaScript frameworks, focusing on server-side paradigms that do not sacrifice interactivity. He advocates for using Kotlin DSLs to write composable components and bypass traditional REST APIs. His presentations—including his breakdown on removing JavaScript from the stack—showcase how tools like HTMX can handle routing, page transitions, and real-time validation without the typical frontend bloat. ## Past Sessions ### World Congress 2025 · July 9, 2025 Berlin, Germany - [How to kill JavaScript from your Stack with HTMX and Kotlin](https://www.wearedevelopers.com/videos/1427-how-to-kill-javascript-from-your-stack-with-htmx-and-kotlin) · 30 min · 🎥 Watch recording ## Videos - [How to kill JavaScript from your Stack with HTMX and Kotlin](https://www.wearedevelopers.com/videos/1427-how-to-kill-javascript-from-your-stack-with-htmx-and-kotlin) · Frederik Pietzko ## Links - [LinkedIn](https://linkedin.com/in/frederik-pietzko)
