Riccardo is a passionate and ambitious senior full-stack developer with 10+ years of experience. He likes to work on both the backend and frontend. Worked extensively with Java, Kotlin, and almost all features of the Spring framework on the backend. His frontend skills are considered good while familiar with its technologies, like Angular and AngularJS, NgRx, Karma, Jest, Codecept.js, Cypress.io, and Jasmine. But his real knowledge lies on the backend side, where he likes many modern architectural approaches, like Domain-Driven Design, CQRS, and microservices architecture.
He is a perfectionist who genuinely cares about proper testing and code quality - TDD is the way to go! Riccardo is experienced with testing tools like Junit, Mockito, REST Assured, and Cucumber. He's worked with multiple databases in his career, such as MongoDB, PostgreSQL, and Oracle. Besides that, he also is experienced with JDBC, and he knows his way in tools like Maven, Git, and Docker.
Following courses and learning about new technologies are his hobbies. Mastering all aspects of software development, both backend and frontend is his goal. In his spare time, he likes to play video games and have a beer with his friends. Of course, he only has time for that if he's not following an online course…
Most developers have written or used concurrent code during their careers. Those who use Java are probably familiar with the traditional unit of concurrency: the Thread. Kotlin brought first-class support to a different concurrency paradigm, called coroutines. These were created in the sixties... Why are they important again, after 50 years? Let’s find out!
This session intends to demonstrate the differences between concurrency models based on threads and concurrency models based on coroutines. We will discuss what coroutines are and what they are not, and answer questions such as:
During the session, we'll present several hands-on exercises that allow participants to see with their own eyes the way how coroutines work and experience the differences and similarities between Kotlin and Java concurrency models. We'll discuss the performance, memory usage, and complexity of both models.
At the end of this session, participants will have a good grasp of the paradigm shift that Kotlin coroutines brought to the JVM.
