Let's break down how to integrate crypto payments into your product without unnecessary headaches. We’ll quickly go through blockchain basics: what blocks and transactions are, the types of networks, and what distinguishes USDT from ETH beyond just their names. We’ll connect to the blockchain via Testnet, Mainnet, our own node, or third-party APIs - examining what’s more cost-effective, faster, and more secure. We’ll create a crypto wallet, learn how to track transactions, sign them, and send them to the blockchain. And, of course, we’ll focus on security: where to store private keys, how to avoid dirty money, and what to do if your crypto is already showing up where it shouldn’t. No fluff - just code, practice, and a bit of blockchain magic.

In this talk, I’ll explain how we adopted Effect.ts, what it truly offers to developers, and whether it really changes the game in the world of TypeScript.

In this talk, we will discuss how to use A/B testing to optimize mobile applications and improve user experience. Using real case examples, we will explore how to properly implement experiments, interpret their results, and make data-driven decisions. We will also cover common mistakes to avoid and share best practices we use at Wix.

The use of micro-frontends and monorepos has significantly accelerated development in our team. In our talk, we'll share how we dealt with common challenges, like integrating products with independent release cycles, swapping dependencies in runtime, and optimizing DevEx during the transition to local HTTPS + H2. We'll give you some practical advice from real-life examples on improving your development process while keeping things flexible and fast.

Here you'll hear a story about how a framework can make your life easier in a huge project. Story about our pains, tears and joys at Wix Editor.

This talk makes AI approachable to the everyday developer to drive real-time business outcomes and goals. We explore running AI locally, getting around some serious limitations with AI like hallucinations and knowledge cutoff, and creating better user experience with AI.

Millions of daily users, hundreds of clients, one embeddable widget. How did we build it and what could possibly have gone wrong?

In this talk, we will explore the micro frontend architecture based on the real example of the big product, uncovering how dozens of teams coexist, work, and deploy features independently every day. Moreover, I will talk about the bottlenecks of React hydration, how it affects users, and how to apply the progressive hydration pattern to improve web performance.

Using the example of a simple, but very complexly written component, Serhiy will try to analyze the best practices of combating the worst practices and will try together with the audience to determine the same line between common sense and the desire to do everything perfectly.

I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
