📌 Multi-user Testing Strategies with Playwright with Nieky Allen

End-to-end (e2e) testing is increasingly important for rapid & iterative application development. However, certain features demand robust multi-user testing to ensure proper functionality across various roles and permissions. By defining scenario-based configuration matrices, you can dynamically create and leverage Playwright’s browser contexts to simulate various devices & authentication states. We will cover the fundamentals of browser and authentication simulation, explore multi-user interactions, and demonstrate how to handle dynamically defined user scenarios. We’ll also discuss techniques for streamlining and scaling your testing processes using well-structured configurations with tools like hooks & fixtures.

📌 Macrodata Refinement with Svelte with Ken Kunz

At Lumon Industries, our Macrodata Refinement Department handles critical data processing tasks that require utmost precision and employee satisfaction. Through rigorous evaluation, we selected Svelte 5 to power our data refinement interface, achieving performance metrics that our analysis team finds... downright scary. In this session, we'll walk through implementing Lumon's distinctive data visualization patterns using Svelte's built-in transition capabilities, demonstrate the elegance of runes-based reactivity, and share quantifiable improvements in both technical and corporate metrics that would make even MDR's most experienced refiners proud.

📌 How Developers Can Optimize for AI-Powered Search with Isaac Morey

As generative AI, voice assistants, and chat-based tools reshape how people discover content, search is no longer just about keywords. It's about context, structure, and visibility to machines that think more like humans.

This talk is a practical guide for developers who want their content to show up in AI-powered search results. We'll cover technical strategies like structured data (JSON-LD), how JavaScript frameworks affect SEO, and how to deliver content in a way that’s legible to modern AI engines. But we’ll also explore what makes content itself effective: how to structure information, write for semantic clarity, and follow SEO best practices that actually work in the real world.
