Book Description
Scala is a type-safe JVM language that incorporates object-oriented and functional programming (OOP and FP) aspects. This book gets you started with essentials of software development by guiding you through various aspects of Scala programming, helping you bridge the gap between learning and implementing. You will learn about the unique features of Scala through diverse applications and experience simple yet powerful approaches for software development.
Scala Programming Projects will help you build a number of applications, beginning with simple projects, such as a financial independence calculator, and advancing to other projects, such as a shopping application and a Bitcoin transaction analyzer. You will be able to use various Scala features, such as its OOP and FP capabilities, and learn how to write concise, reactive, and concurrent applications in a type-safe manner. You will also learn how to use top-notch libraries such as Akka and Play and integrate Scala apps with Kafka, Spark, and Zeppelin, along with deploying applications on a cloud platform.
By the end of the book, you will not only know the ins and outs of Scala, but you will also be able to apply it to solve a variety of real-world problems

He has over 15 years of experience in the financial industry of the UK, Switzerland, and France. He has a Diplôme d'Ingénieur in Computing (equivalent to an M.Sc.) from Telecom Nancy, France. After years of working with Java, he started developing professionally with Scala in 2010, and never looked back. He was a speaker at Scala Exchange 2015. When he is not coding in Scala, Mikaël likes to dabble with Haskell, the Robotic Operating System, and deep learning. He strongly believes that functional programming with strong typing is the best way to write safe and scalable programs.
Nicolas Jorand is a senior developer. He worked for the finance industry for about 15 years before switching to the energy industry. He is a freelancer enjoying a partial time at Romande Energy, a Swiss utility company providing exclusively green electricity. Nicolas is a full-stack developer, playing with microcontrollers, developing standard web user and 3D interfaces on Unity, developing software to animate a humanoid robot (Nao) and finally, working with Scala on integration and backend software. All these projects are done with the same leitmotif; "In the dev process, get the issues as early as possible."
