🗣️ The Unfinished Guide to Career Changing in Scala
Are you thinking about switching to a career in Scala? Just starting out and looking for guidance? Or maybe you’re an experienced Scala developer excited to share your journey and support others? Wherever you are on your path, we’d love for you to join us at the second Women in Scala event!
This event is all about connection, collaboration, and community. Expect lively discussions, knowledge sharing, and the chance to meet other Scala enthusiasts — from career changers and juniors to seasoned developers.
We’ll kick things off with an interactive presentation: “A Guide to Career Changing in Scala” — but here’s the twist: this guide is unfinished. That’s where you come in! Through conversation and shared experiences, we’ll shape it together, creating a resource that reflects the wisdom and insights of the community.
Whether you’re looking for advice, or a chance to give back and help others grow, this is your opportunity to get involved and help shape the future of Women in Scala events. Let’s build something great — and have some fun while we’re at it!

🗣️ Jędrzej Rochala: Compiler-First Development: A Fresh Take on Scala in IntelliJ
In this talk, I will introduce a fresh take on the Scala Plugin in IntelliJ IDEA based on the standard Scala compiler.
This approach delivers zero false positives, dramatically improves performance and enhances syntax highlighting - all while maintaining robust Java interoperability. On top of that, you can expect correct diagnostics popping up instantly, without any need of saving the files. Did I also mention that compiler plugins are also supported out of the box?
And that's not even all the features. Join us to discover all of them.⭐ Jędrzej Rochala ⭐
Jędrzej is an engineer at VirtusLab contributing to the Scala 3 compiler and Metals.🗣️ Haoyi Li: Solving Scala's Build Problem with the Mill Build Tool
Mill is a Scala build tool that improves upon every aspect of the venerable SBT toolchain: more performant, easier to understand, and scalable to larger codebases. Unlike most build tools, Mill makes build configuration easy: easier to write, easier to navigate, and easier to understand. This talk will explore how Mill works, demonstrate its advantages over SBT in a live-coding setting, and dive into the novel techniques that a modern build tool uses to improve upon older build tools of years and decades past.⭐ Li Haoyi ⭐
