🎤 **PRESENTATIONS**
🖥️ **Angular DI in Practice: From Basics to Hidden Behaviors**
A journey through Angular’s Dependency Injection system. We’ll reinforce the basics, then move into advanced cases and live coding that demonstrate how to harness DI effectively—and avoid surprises in your apps. From providers vs viewProviders to DI hierarchies and subtle edge cases, this talk will help you better understand what’s really happening under the hood and prevent unexpected bugs in your Angular projects.

👨‍💻**Paweł Kubiak** is an Angular developer passionate about building clean, scalable front-end applications. He is also the organizer of Angular Wrocław, where he brings together the local community to share knowledge, best practices, and lessons learned from real-world projects. With hands-on experience in tackling complex UI challenges, Paweł enjoys exploring hidden parts of Angular that help developers write more predictable and maintainable code

🖥️**Peak Performance with Partytown Tackling the 3rd party challenge in big enterprises - A Case Study**
45% of all requests made by websites are third-party requests. A huge portion of them are scripts. Scripts you cannot control, nor improve. Whatever they are executing, they are competing with your application code about the priority on the main thread. Bloating the main thread with more execution than necessary ultimately screws the runtime performance and responsiveness of our applications - especially for mobile users. In this talk, I’m going to introduce you to partytown. A library that helps you to execute 3rd party scripts in a sandboxed worker thread - making use of true multi-threading in the browser. To start things off, I’m taking you on a deep dive into the realms of the Web Workers API. You are going to learn what Web Workers are, how they operate, what limitations they bring and how partytown offers a unique approach to integrate Workers into your web application. To make things digestible, I’m going to share the whole story of how we integrated partytown into a billion dollar application. You will get insightful details about pitfalls, dirty hacks and partytown improved the applications performance to the peak. Talk Structure & Table of Contents.

👨‍💻**Julian Jandl** is a Lead Performance Engineer, trainer, and consultant at Push-Based.io, where he helps companies build faster, more efficient web applications at scale. Passionate about web performance and modern frontend architecture, Julian spends his time diving deep into the browser’s internals, conducting real-world audits, eliminating bottlenecks, and delivering high-impact workshops on Angular and web performance. Whether it’s tuning milliseconds off load times or mentoring teams in hands-on sessions, Julian brings a practical approach to making the web fast.
