Session 1: Code Once, Run Everywhere : A Beginner's Journey with React Native
Speaker: Hasitha Walpola, Technical Lead at Delivergate

This interactive session is designed for beginners who are eager to explore the world of mobile app development. Hasitha will
introduce React Native, a powerful and popular framework that allows you to build cross-platform mobile applications for both iOS and Android using JavaScript.
During the session, we’ll walk through the core concepts of React Native, showing how it enables developers to create mobile apps efficiently with a single codebase. Participants will follow along as we build a simple, functional mobile app — learning how to set up a development environment, structure a project, and bring a basic app idea to life.
By the end of this session, attendees will understand the fundamentals of React Native and feel confident about starting their own journey in mobile app development.

Session 2: Securing Tokens Using Web Workers in Modern Web Applications
Speaker: Omal Wijegunawardana, Senior Software Engineer at WSO2

In this session, we'll explore how Web Workers can be leveraged to enhance the security of access tokens in web applications by isolating sensitive logic from the main thread. We'll dive into real-world implementations, including how this approach is used in production within the React SDK of Asgardeo—a modern Identity as a Service platform. Join us to learn the practical benefits of using Web Workers for token handling and how this technique helps mitigate common attack vectors in single-page applications.
