Workshop: Optimizing Web Performance
Mentor: Oleksandr Lavrenchuk, Front-end Tech Lead. Has 7+ years of experience in front-end development: from working in dynamic startups to creating high-load applications with millions of users.
Optimized images and minimized CSS, but your web application is still slow? It's time to figure out what really affects loading speed and interaction!
Performance plays a key role in the modern web: user experience (UX), search engine rankings, and even business metrics depend on it. Core Web Vitals (CWV) determine the quality of a site's work from the point of view of real users, and their optimization can significantly improve performance indicators.

- During the workshop you will learn:
- How to analyze Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), Interaction to Next Paint (INP), as well as First Contentful Paint (FCP) and Time to First Byte (TTFB).
- Why optimizing server rendering and streaming can significantly improve CWV.
- How to use React Server Components, Suspense and Next.js to improve performance.
- Practical approaches to measuring and eliminating bottlenecks in your application.
You will gain both theoretical and practical knowledge of web optimization, learn how to improve Web Vitals, and understand how to find and eliminate problem areas and what to pay attention to in everyday web application development.
