In this talk, I'll discuss how Reacts' often overlooked concurrent features like startTransition, useDeterredValue and Suspense can transform an application's performance and responsiveness. Participants will learn practical techniques to prioritise critical updates, gracefully handle loading states, and create fluid user experiences even with complex data interactions.

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.

Software performance engineering (SPE) aims to build predictable performance into systems by specifying and analyzing quantitative behavior from the beginning of a system to its deployment and evolution. We should also apply this thinking to the data portions of our applications and systems. Performing data operations with Entity Framework Core 8 can seem simple, but there is a hidden part of this framework that can allow developers to unlock the performance users expect. We will lean into this, explore those EF Core features, and leave the talk as better developers.

In recent years, I have gained most of my knowledge through reverse engineering, how I did it and what I learned during this period, I decided to share. All this concerns graphic programming, performance, best practices in the frontend.

In this talk, we’ll explore a number of popular techniques for populating and delivering content into web views for our users. We’ll compare different rendering models to help us understand the benefits and limitations of each one, and we’ll build examples with different tools to show how our choices influence the developer experience, user experience, and environmental impact of our projects.
