🚩 Agenda

➡️ Bartosz Jakubowiak, Joe McKevitt – Don’t let your customers do your application performance testing for you
Joe McKevitt and Bartosz Jakubowiak will talk about the importance of performance testing in the fintech industry during their time together developing a trading application.
By the time they are done you'll understand why it is crucial to test your apps, have a basic toolset and see the practice of performance troubleshooting in action.

➡️ Mariusz Bełtowski – Node.js in depth
Have you ever wondered how the node.js handles asynchronous programming within a single thread?

Is node.js single threaded at all?

From this presentation you will find out:
- How the node.js communicate with the operating system.
- How an asynchronous concept works from the inside out.
- How does node.js handle 10k concurrent requests, and how to attack such a server?
- Bad practices.

➡️ Monika Kołodziejczyk – How MUI & Storybook can make your life easier
Have you heard of the Material Design and Material UI components library and Storybook? - I bet so! :) During this presentation, I'm going to tell you a little bit about the upsides of these tools, how they work with Material UI can be optimized by using the theme object, and how Storybook can smoothen cooperation between Developers inside the growing team and designers as well.
