What happens when you need to refactor 377 files in a SvelteKit codebase? Without AI, you retire. With Claude Code, you ship it in 11 hours.

This talk walks through real-world examples of using Claude Code for massive refactoring work that would be soul-crushing to do manually. I'll cover:

How I approach large-scale refactors with Claude (377 files → 364 files → and counting)

Building and activating Claude Code skills reliably (based on my viral post that's getting 4k+ views in 3 days)

The workflow patterns that actually work vs the ones that waste your time

Real examples from production codebases

This isn't about AI replacing developers - it's about using AI to handle the tedious parts so you can focus on the interesting problems.

Cognitive stress has always been a challenge when dealing with new languages, features and APIs. Oftentimes, we find ourselves experimenting with new features, rather than only reading their documentation. Either with a debugger, a REPL environment, or a thousand console.logs, we explore what these tools do. But what if there was something that will further cut the time between writing code and seeing the result? JS Eval is a tool that achieves exactly this by displaying the evaluation results of your program directly where they come from. Join me as we dive into its plethora of features and how they can help you understand the new tools you encounter!
