Everything in


One of the best ways to share my passion about Java is giving a talk - be it at a local meetup, an international conference, anywhere in between, and (nowadays) remotely. Here's a list of my talks.


First things first, here's the list of my talks - if any of them are interesting for your event, let me know. More are always in the making and some of them are pretty malleable, so feel free to ask for details and customizations that match your preference.

Java Next#talk#java‑next #project‑amber #project‑loom #project‑panama #project‑valhalla
From Amber to Loom, from Panama to Valhalla - the four big projects are entering the home stretch. Time to take a closer look at how they will improve Java.
Pattern Matching in Java (17)#talk#pattern‑matching #project‑amber
Pattern Matching is finding its way into Java, one step at a time, along three paths: patterns, switch improvements, sealed classes. Let's see how they all come together.
Java Modules in Real Life#talk#j_ms #migration
Advice on why, when, when not, and how to use Java modules in real life for your projects
Why Don't They Just... ?! The Deliberations Behind Evolving Java#talk#streams #optional #records #collections
There are many nifty features that Java could have but doesn't. Somewhat surprisingly, there are reasons for that and in this talk I'll discuss those for a few concrete cases as well as the deliberations behind such decisions.
To Jupiter And Beyond - On An Exploratory Mission With JUnit Pioneer#talk#junit‑pioneer #junit‑5 #community #documentation #tools
JUnit Pioneer gathers JUnit 5 extensions. This talk discusses the technical aspects, but also the mission, dev practices, automatic releases, and what Twitch has to do with all of this.
Java After Eleven#talk#java‑11 #java‑12 #java‑13 #java‑14 #java‑15 #java‑16 #java‑17
A live-coding talk during which I update a Java 11 code base to Java 17, making good use of new language features, additional and improved APIs, and JVM capabilities
Best Practices Considered Harmful#talk#techniques
A lightning talk about how best practices promote a one-size-fits all mentality that harms our ability to create solutions that are tailored to the problems at hand
Fun With var#talk#anonymous‑classes #default‑methods #generics #lambda #java‑10 #var
A live-coding talk where I show off all you need to know about var in Java. And then some.
To JAR Hell And Back#talk#java‑9 #java‑11 #j_ms #migration
A live-coding talk where we take a typical Java 8 code base and update it to Java 9 and beyond, overcoming some common and some less common hurdles like dependencies on internal APIs and split packages
Modern Java - Language, Runtime, LTS#talk#java‑9 #java‑10 #java‑11 #java‑12 #java‑13 #java‑14 #java‑15 #java‑16 #java‑17
In this talk, I introduce the Java language features, new/updated APIs, and new JVM capabilities that recent Java releases brought to the ecosystem and also discuss the current release and support model
Expert Java 8#talk#java‑8 #lambda #streams #optional #default‑methods
With this talk, I help you get the most out of lambdas, Streams, Optionals, and default methods, helping you master Java 8's core features
Comment Your &*☠# Code!#talk#agile #clean‑comments #documentation
A heartfelt rant / thoughtful talk arguing for more comments in code
JUnit 5#talk#junit‑5 #testing
In this talk, I introduce JUnit 5 from basic tests to more advanced features like nesting, parameterization, parallelization, and extensions. We also discuss its architecture and compatibility with JUnit 4.
The Java Module System Beyond The Basics#talk#j_ms #migration
In this talk, I go beyond the module system basics and present more advanced features for those who want to become their team's module system expert

From small meetups at local communities all the way to large conferences, I love speaking about Java (or the few other topics I have something to say about). If you're organizing one of these events, please hit me up. In most cases, you don't need to worry about travel expenses - Big O will cover that.
