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.

Scala 3.6 stabilises the Named Tuples proposal in the main language. It gives us new syntax for structural types and values, and tools for programmatic manipulation of structural types without macros. Can we, and should we, push it to the limit? Of course! let's explore DSL's for config, data, and scripting, for a more dynamic feel.
In this talk I will explain the inner workings of an organisation that goes into releasing, maintaining and developing Scala and core parts of its ecosystem.
In this talk we'll see how to model a tree structure in Scala, take both imperative and functional approaches to tree traversal algorithms, and do some ASCII art at the same time.
