    Oscar Andell, Frontend Staff Engineer at Lodgify

We will take a look at smart caching techniques, creating fast feedback loops, minimizing redundancy, and optimizing runtime performance. Learn tips to keep your frontend pipelines speedy, dependable, and your team happy!

    19:20 When AI Meets Legacy: Refactoring Emotion to CSS Modules
    Speaker: Bernabe Felix, Senior Frontend Engineer at Lodgify

    Could an LLM refactor your codebase? I found out — first by experimenting with AI-assisted migrations, learning its strengths and limits. In this talk, I’ll show how I applied those lessons to a bigger challenge: migrating from Emotion to CSS Modules. You’ll see how AI helped prototype changes, where it fell short, and how Codemods made the refactor reliable.

    19:50: Drinks and networking!

    20:45 Meetup finished
