The Instructor

Daniel Ciocîrlan

Java and Scala developer and best-selling instructor. I'm an avid fan of Scala, Akka and Apache Spark and I've taught more than 30000 people all over the world.

I've taught Scala, Akka and Spark in live trainings at some of the best companies in the world.

From students

Giannis on Akka Streams

"I've heard guys working years with Scala saying that the Akka Streams library is so complex that only the Lightbend folks that wrote it can use it [...] Daniel once again nails it, explains so nicely every single detail, and spreads some light into such a hard topic. [...] Honestly Daniel is like my Scala Guru"

Elliott on Advanced Scala

"This was every bit as brilliant as the more basic course. Scala is an exceedingly cool language and Daniel is able to explain techniques that would be quite advanced even for an experienced C++ programmer. I am the latter, and it has to be said that the way Scala simplifies the code required for many techniques is really impressive. [...] another tour de force from Daniel"

John on Akka Essentials

"Daniel, this was a great course. You hit on all the important points and the flow was great; each lesson building on the previous one. And the exercises really enforced that building"
