Ryan Weaver, Symfony Core Team Member, will share his experience and talk about “Prime Time with Messenger: Queues, Workers & more Fun!”. In Symfony 4.4, Messenger will lose its experimental label and officially become stable! In this talk, he'll go through Messenger from the ground-up: learning about messages, message handlers, transports and how to consume messages asynchronously via worker commands. Everything you need to make your app faster by delaying work until later. He will also talk about the many new features that were added to Messenger since Symfony 4.3, like retries, the failure transport and support for using Doctrine and Redis as transports.

Zan Baldwin and Nicolas Grekas, will be talking about "One year of Symfony" as a Closing Keynote.

For who is Sylius designed for? He will answer these questions and give some insight over the newest changes in the platform.

Lander Vanderstraeten, PHP developer and PHPro, will present a talk about “Eeek, my tests are mutating!”. Writing tests is nice, but how are you sure that your tests cover all use cases? Code coverage can give false positive metrics. A new way of working that goes by the name of mutation testing has gained a lot of popularity lately. This talk will explain you what it is, how you can integrate it and contains a demo over the basics of mutation testing with infection and phpspec.

Grégoire Hébert, Senior Developer, trainer and CEO of MasterClass By Les-Tilleuls, will introduce to you “Together towards an AI, NEAT plus ultra”. You've heard about AI for some time. But it remains obscure for you. How does it work, what is behind this word? If for you, reading white papers or doctoral paper is not your thing, that the Tensorflow doc is just a big pile of words for you, and if you've seen unclear presentations using the same vocabulary without really giving you an idea of how it works and how to implement an AI at home ... This presentation is for you. At its end, you will be able to play with an AI, simple, but that will serve as a gateway to the beautiful world of machine-learning.

Sebastian Bergmann, Co-Founder and Principal Consultant at thePHP.cc, will deliver a talk about "PHPUnit Best Practices". While PHPUnit is not difficult to set up and writing tests with it is easy, you will get better results and save development time if you know the tips and tricks to leverage PHPUnit more effectively. This session, presented by the creator of PHPUnit, teaches best practices you can use to ensure that your unit testing effort is efficiently implemented.

Juciellen Cabrera, Software Engineer, "Symfony Serializer: There and back again". When you are developing APIs sometimes you need return the same object with different ways. Furthermore a object can be complex due your relashionships with others objects turning serialization process such hard. The Symfony Serializer Component makes possible manage how you wants to serialize objects for json, xml e other options. Also you can manage responses using serialization groups, choosing which properties you want, handling Serialization Depth and much more.

Titouan Galopin, product manager at SymfonyInsight, will speak about “Demystifying React JS for Symfony developers”. The world of JavaScript is vast and exciting... but it can also be quite scary! It is an innovative world in which new technologies appear all the time, which can make it difficult for developers to keep up to date. One of the most famous of these technologies is probably React JS. It changed the way we conceive User Interfaces, both in the browser and in mobile applications. But understanding it can be challenging. Let's demystify it together so that you can enter the world of JavaScript with confidence!

Tobias Nyholm, Symfony Core Team and Symfony CARE team member, will talk about “Building really fast applications”. What can we do to make an application run faster? What should we be considering when starting a new application? There are some quick fixes that he will quickly cover. But to get down to really fast response times requires hard work. He will give his best ideas and tricks for fast apps. He will show how we can build applications that responds in less that 15ms and then work towards even faster than that.
