In this talk, I'll walk you through coding and design practices I've developed over the years, whilst onboarding new graduates into world of Scala (be it typelevel based API, Spark based ETL, or ML pre and post-processings), and how I made the process easier for people who didn't have much Scala experience beforehand.

Onboarding new members into a mature codebase can be a non-trivial task. Especially that business documentation is usually a weakpoint, and requirements are ever changing. Furthermore whole functional stack can be a lot to digest for a person first interacting with Scala.

In this talk, we'll cover the essentials of macros, why they are useful, why you should care about them, and how to become as good as you need with them for practical purposes.
In this talk, I'll introduce Bazel, exploring its core concepts and the unique aspects that set it apart from other build tools. I'll dive into some typical challenges Scala developers might face when working with Bazel.
During the talk, we’ll build a small effect system using solely Scala 3 context functions step-by-step.
