In this course, we will learn how to write big data applications with Apache Spark 3 and Scala. You’ll write 2000+ lines of Spark code yourself, with guidance, and you will become a rockstar.
This course is for Scala programmers who are getting started with Apache Spark and big data. The course is not for advanced Spark engineers.
Why Spark in Scala:
•it’s blazing fast for big data
•its demand has exploded
•it’s a highly marketable skill
•it’s well maintained, with dozens of high-quality extensions
•it’s a foundation for a data scientist
I like to get to the point and get things done. This course 
•deconstructs all concepts into the critical pieces you need
•selects the most important ideas and separates them into what’s simple but critical and what’s powerful
•sequences ideas in a way that “clicks” and makes sense throughout the process of learning
•applies everything in live code
The end benefits are still much greater:
•a completely new mental model around data processing
•significantly more marketable resume
•more enjoyable work – Spark is fun!
This course is for established programmers with experience with Scala and with functional programming at the level of the Rock the JVM Scala beginners course. I already assume a solid understanding of general programming fundamentals.
This course is NOT for you if
•you’ve never written Scala code before
•you don’t have some essential parallel programming background (e.g. what’s a process/a thread)
The course is comprehensive, but you’ll always see me get straight to the point. So make sure you have a good level of focus and commitment to become a badass programmer.
I believe both theory and practice are important. That’s why you’ll get lectures with code examples, real life code demos and assignments, plus additional resources, instructions, exercises and solutions. At the end of the course, you’ll have written thousands of lines of Spark.
I’ve seen that my students are most successful – and my best students work at Google-class companies – when they’re guided, but not being told what to do. I have exercises waiting for you, where I offer my (opinionated) guidance but otherwise freedom to experiment and improve upon your code.
Definitely not least, my students are most successful when they have fun along the way!
So join me in this course and let’s rock the JVM!

You will learn

✓ apply Spark big data principles
✓ practice Spark DataFrames operations with 100+ examples and exercises
✓ practice type-safe data processing with Spark Datasets
✓ work with low-level Spark APIs with RDDs
✓ use Spark SQL for data processing
✓ migrate data from various data sources, including databases


• Scala fundamentals, at the level of the Rock the JVM beginners course
• Scala advanced – implicits

This course is for

• Future data scientists
• Programmers getting into the field of Big Data
• Engineers wanting to learn Spark in Scala, its native language

Software Engineer & Best-Selling Instructor
I’m a software engineer with a passion for teaching. Big fan of Scala and the JVM.
I have a Master’s Degree in Computer Science and I wrote my Bachelor and Master theses on Quantum Computation. Before starting to learn programming, I won medals at international Physics competitions.
For 7+ years, I’ve taught a variety of Computer Science topics to 30000+ of students at various levels. I’ve held Hour of Code for 7 year-olds, I’ve taught university students who now work at Google and Facebook, I’ve held live trainings for software engineering teams at Adobe and Apple, and I’m now so excited to share what I know with a wider community online.
