A number of developers and organizations are beginning to make use of Functional Programming in Java. With anything that’s new, we often learn it the hard way. By stepping back and taking a look at programming style as idioms, we can quickly gravitate towards better coding style and also avoid some common traps that we often get drawn towards.

Looking for a new job is like looking for a soulmate. You build a list of must-haves and search for the company that will check all those boxes. In this talk, we will answer the most frequently asked burning questions during our recruitment process. As a company that recruits in this field, we have realized that career growth opportunities, cultural alignment, and having a real impact, are some of the most important drivers for IT professionals and jobseekers.

While a microservices architecture is more scalable than a monolith, it has a direct hit on performance. To cope with that, one performance improvement is to set up a cache. It can be configured for database access, for REST calls or just to store session state across a cluster of server nodes. In this demo-based talk, I’ll show how Hazelcast In-Memory Data Grid can help you in each one of those areas and how to configure it. Hint: it’s much easier than one would expect.

Yet another hype has come: GitOps. Let’s talk about what it is, why all this hype and how to apply it in a cloud native environment.

As Java is an object-oriented language that inherently supports the imperative programming style, asynchronicity presents a challenge that can turn the code into a nightmare. One way to deal with the complexity of asynchronicity is to introduce reactivity onto the coding level (reactive programming), and/or to handle it on the design and architecture level (reactive systems design). This talk presents to the audience a few of the major Java-based reactive frameworks and toolkits in the market today, such as RxJava, Spring Reactor, Akka, and Vert,x. It will start by going over the basic tenets of reactive systems, and some examples of the problems that these systems aim to solve. It will discuss the 2 most commonly used Java frameworks for implementing reactive coding – RxJava and Spring Reactor, and will show some code samples. It will then bring the audience to the next level of “reactivity’ by introducing 2 reactive frameworks – Akka and Vert,x, which are usually used for implementing reactive microservices. It will draw some comparisons between these 2 frameworks and cite some real-life examples of their usages. The takeaways for the audience will be an understanding of the key differences between reactive programming versus reactive systems, and the strength and weaknesses of each of the surveyed frameworks.

Who’s a senior developer? What’s the main difference between a middle level professional and a senior? How to become a senior? In this talk, we’ll answer these questions and give you actionable recommendations for progressing up the career ladder.

Have you ever felt uninspired by the every-day grind? Like coding is all work and no play? Come with me as I take you on a whistle-stop tour of delightful SVG animations and look at some tools and tips to help you get started.

The Angular framework is feature rich and makes development fun and productive. One of the things that makes Angular so productive is the power of the super charged CLI (command line interface). In this beginner friendly session let’s take a look at how the CLI changes your developer experience.

A no-slides, hands-on, live debugging session using only the browser Developer Tools on the website of your choice. We’ll dive deep into spotting performance bottlenecks into any website and how to fix them.

Web performance has been a hot topic for a long time and it’s becoming even more relevant every day. Why and how should we care about it? Let me answer these questions by sharing some real experiences related to monitoring, optimization, and tooling.

Keeping up with the state of web technology is one of the biggest challenges for us developers today. We invent new tools; we define new best practices, everything’s new, always … And we do all that for good user experience! We do all that to build the best possible web – it’s all about our users. But is it, really? Or do developers like to play with technology secretly loving the new and shiny? Or do we only pretend that it’s about users, and behind closed doors, it’s developer experience that matters to us? Did we lose direction? Is it time for a critical look at the state of the web and the role JavaScript plays in it?
