      I Don't Know JavaScript

      Let's look at why expressions and operators need to be treated as interfaces, show how asynchronous get/set work, what await new has to do with it, and how to make self-reproducible instances of classes.

      Observability of Microfrontends

      I'll tell you how we set up observability for almost 1,000 microfrontends, what tools we use, and how it differs from observability of services.

    • Keynote

      Focus on Quality

      We'll predict errors in our code, and we'll also talk about the future of testing and why it should be a concern for any modern engineer. We'll use real-life cases to demonstrate how to balance speed, quality, and risk in practice and how to prioritize functionality coverage.

      Reactive CSS

      We are on the verge of a revolution in layout related to a new approach—reactive CSS. Here the usual display logic "shifts" from JavaScript to styles, and the entire appearance of the component depends on CSS state variables.

      What Is Architecture?

      I'll tell you and show you what an architect should do, what artifacts to leave behind, why supervision is important, and how you can partially skip this stage.

      FSD Is a Grave, Only FDA Will Save!

      Sometimes I feel that FSD has gained popularity undeservedly, and despite all the disadvantages it continues to be used.

      I will analyze the problems of this architectural methodology,  the available alternatives and propose a worthy solution—the FDA.

      Typing Beyond Code: Contracts Between Layers

      In this talk, I’ll share configurations, techniques, and scripts that allow us to type not only the code itself, but also the boundaries between application layers.

      We’ll explore how to make contracts verifiable across MobX stores, routing, CSS Modules and CSS Variables, ENV configs, i18next, API responses, feature toggles, Storybook, and even icons — reducing system fragility at the seams between them. And of course, we’ll also address performance.
