Why are modern frameworks once again trying to reinvent reactivity — and what do signals have to do with it? In this talk, we’ll take a look at signals as an attempt to give JavaScript developers fine-grained reactivity tools without extra code, proxies, or memoization. The problem they aim to solve is as old as frontend itself: how to update only what needs updating — and do it predictably. We’ll explore how this approach works, which frameworks have already adopted it, and what the current TC39 proposal means. Most importantly — do signals actually solve the problem, or are they just introducing a new layer of complexity with different syntax?
Serhii Babich
(Senior Frontend Developer, DataRobot),This talk is a lighthearted yet painfully familiar existential crisis of a frontend developer. We’ll start with simple DOM manipulation, walk through jQuery, SPA, React, and end with some thoughts on server-side rendering — with the help of a certain Twitter thread that turned out to be wiser than most textbooks.
Khrystyna Landvytovych
(DataRobot),This talk begins with a brief overview of frontend history, mentioning the era of AngularJS dominance and the reasons for its subsequent decline in popularity (particularly its complexity and the rise of React)
Yevhen Rusakov
(FE Tech, Silpo),AI is no longer just a buzzword; it's a transformative force poised to reshape how we interact with technology. Everyone is trying to create the latest game-changing AI-driven app, but how can we developers leverage GenAI without becoming full-fledged AI experts or overhauling our existing applications? This talk will move past the academic exercises and explore the "sneaky" ways GenAI can be seamlessly integrated into existing applications to create subtle yet powerful enhancements that elevate the user experience. Through real-world examples and engaging demos, we'll uncover the hidden potential of GenAI to personalize user experiences and unlock new levels of creativity and efficiency. Leave this talk empowered to harness the power of GenAI, even if you're new to AI. Discover practical strategies and inspiring ideas to infuse your apps with intelligence, delight your users, and stay ahead of the curve in this rapidly evolving technological landscape
Ben Ilegbodu
(Senior Software Engineer, Netflix),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.
Oleksii Holubiev
(BrainRocket),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.
Taras Shevchuk
(Center of innovations),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.
Serhii Tuniehov
(Mobile Team Lead 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.
Herman Kyrii
(Team Lead, Center of Innovations),Ostap Chervak
(Software Engineer, Center of Innovations),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.
Yaroslav Doroshchuk
(Head of Wix Editor R&D),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.
