Need a cool data management tool, don't want to bother with state, context & redux. I invite you to dive into the world of react-query with me! I will share my personal experience with you and tell you WHY this library is worth your attention!

I will tell you about our experience of using React Native in a non-obvious way, what came out of it and why our customers and users liked it so much.

In this talk we will explore a way to develop and deploy using only local and production environment. Together we will take a look how AB-tests, feature toggles, good test strategy and CI/CD can increase the development velocity and time-to-fix rate.

After night of partying Oleksii can’t find boilerplate in his project. Was it stolen? Or maybe it’s just someone’s sick joke? Let’s deep dive into this mystery!

<p> Instead of provocative theses, I will try to share a vision with you: </p> <ul> <li>what's important about TypeScript and its ecosystem in recent years</li> <li>why TypeScript won't be able to replace ReScript for me and why I don't see it as a problem</li> <li>what (didn't) appear in React, why and what risks I see</li> <li>how competitive ecosystems have developed and why you should be interested in them</li></ul>

This talk will be about the success stories of the best Ukrainian KillTech product. We will demonstrate our long-term experience in the development of features, which impress with their killTechness.

Join us for an exclusive look at our No-Code Editor. I'll guide you through its design, architecture, and the decisions we've made — but don't worry, I'll keep the technical jargon accessible and easy to follow. Explore how our project is structured and the libraries we use. It's a backstage pass to our startup, made simple!

<p>Tide - a popular financial services platform in the United Kingdom with ambitious plans for global expansion. Over the course of several years, we were developing our mobile applications using native technologies. Facing scalability issues when aiming to enter new markets, platform inconsistencies, and limitations of our current solution, we decided to rebuild our products using Flutter. Flutter is a relatively young framework from Google for building cross-platform applications with a shared codebase.</p> <p>In this presentation, we will share the fundamental transformation our product went through in less than a year. We will discuss how we switched iOS and Android developers to Dart and Flutter, transitioned over a million lines of code to a new technological stack, and released a new version of the product for hundreds of thousands of users. We will highlight the challenges we encountered, the solutions we implemented, and the lessons we learned from this transformation.</p>

Let's talk about the complexity of modern frontend applications and the challenges facing contemporary development — security, performance, accessibility, and other non-functional requirements that a front-end developer must take into account while developing their application in 2023.
