Look inside

You’re a software engineer at TechPower, a consulting company that wants to expand its reach in the tech market by incorporating more programming languages and technologies. This will help it create products while hiring from a more diverse pool of engineers. For TechPower’s latest project, your task is to design an independent music-sharing platform where new artists can upload their music, putting it in front of new eyes (and ears!) for free. Using Simple Build Tool (SBT) and IntelliJ IDEA, you’ll set up your environment to prepare for running a project in Scala, a language that combines object-oriented programming and the functional paradigm. Keeping in mind the platform's users and the kinds of content it will host, you’ll define the main entities and dependencies as part of a Unified Modeling Language (UML) diagram. You’ll implement your design with Scala classes and traits, preparing the utility for function additions later on.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

project author

Roksolana Diachuk

Roksolana Diachuk puts her passion for big data, Scala, and Kubernetes to good use as an engineering manager at Captify. She’s a proud member of the Women Who Code Kyiv and Scala Ukraine communities, and she’s shared her expertise by speaking at Scala and big-data conferences in Europe and the U.S., including ScalaCon 2021/2022, Functional Scala London 2020/2021/2022, Scala Love 2021, and DataCon LA 2021.


This liveProject is for beginner-level developers who know the basics of at least one language and are interested in learning Scala as well as the functional approach to system design. To begin these liveProjects you’ll need to be familiar with the following:

  • Programming language basics (syntax, data types, implementing algorithms)
  • Bash basics (installation, execution of commands and scripts)
  • OOP basics (main principles, classes and objects, class relationships)
  • Intermediate software engineering (function design and implementation, algorithms, and data structures)

you will learn

In this liveProject, you’ll learn system design principles and how to set up a Scala environment.

  • Functional programming concepts (immutable data structures, pattern matching, higher-order functions, partial functions, and options)
  • Define entities and implement their functions
  • Compile the project and debug with SBT and IntelliJ IDEA


You choose the schedule and decide how much time to invest as you build your project.
