Many developers believe seniority is something that happens automatically with time. In practice, some engineers repeat the same year of experience for a decade, while others grow rapidly by changing how they approach problems, people, and responsibility. This talk explores the mindset and behaviors that define effective senior engineers. The content is drawn from real industry experience and consolidated into the book "Pocket Guide to Seniority", turning years of lessons, failures, and team dynamics into practical guidance. We will cover themes such as seeing the whole picture beyond your ticket, owning outcomes instead of outputs, choosing simplicity over cleverness, managing ego in technical discussions, and multiplying impact through teaching. Each topic comes with concrete examples from real projects and teams, focusing on decisions and behaviors rather than abstract theory. Attendees will leave with actionable mental models they can apply immediately in their daily work, regardless of tech stack or company size.

Discover the power of Server Components in React without the need for a framework. In this talk, we will explore how to build a simple server-side rendering solution using "only" vanilla JavaScript and Node.js. We'll dive into the core concepts of Server Components, including how to render components on the server abd manage data fetching. By the end of this session, you'll have an understanding of how to implement Server Components in your own projects without relying on a framework.

Use React principles beyond React projects! Come to this talk to learn how to apply componentization, declarative programming, and reusability to general front-end JavaScript tasks. Elevate your skills and create scalable, maintainable codebases irrespective of the framework or library you choose.

Do you know that the first novel ever written dates back in 1021. Its author is the Japan noblewoman Murasaki Shikibu. Till then countless of writers put their thoughts on paper and countless of readers experience their stories. People write for decades and we, as software developers, kind of ignore their craft. We write too. Not novels but software. Isn't it this still writing? Believe it or not there is a lot in common between creating fiction and writing code. In this presentation we will see how close we are to giants like Hemingway and Stephen King. Can we get some of their wisdom and apply it to our daily job as engineers. Come to this talk and will get a few practical advices. I hope my presentation will make you a slightly better React developer.
