Moderate programming experience with Scala
A computer with an Internet connection. I’ll walk you through downloading and installing SBT, Scala, and an IDE


Modern applications often need to describe complex workflows involving multiple external systems. These are notoriously difficult to get right as it requires handling errors, various retry strategies and non-determinism because of concurrent executions. In this course, you will learn how to solve this problem using both imperative and functional programming.By the end of the course, you will be able to read and write code using popular Scala libraries such as cats-effect, Monix and ZIO. This skill is in high demand.Several companies use this curriculum to on-board and train engineers. Here is a non-exhaustive list:LunatechKaluza / OVO EnergyAutoscout24Pirum SystemsCleverbaseThese companies are constantly hiring new Scala developers! Don’t hesitate to reach out to them and mention that you took this course.I designed this content for backend developers. It is extremely practical and hands-on. Specifically, this means that you will:Write lots of Scala codeTest it using both example-based and property-based testsExperience issues caused by blocking logic and concurrent executionWork your way to efficient solutions in small and incremental stepsI will guide you through all the exercises and provide a complete set of solutions. My goal is to unlock your full potential as a functional Scala developer by demystifying complex concepts using explanations that are free of confusing jargon.For those familiar with FP-Tower courses, this course corresponds to chapter 5 of Foundations of Functional Programming in Scala.Enroll now, and enjoy the course!
