📌 **Building a Model Context Protocol (MCP) in Nodejs** with Justin Meyer

This talk walks through the process of building a Model Context Protocol (MCP) in Nodejs to support downloading attachments from Jira. MCPs are a key part of enabling AI assistants to fetch contextual information from tools like Jira.

Along the way, we’ll explore how the OAuth 2.0 Authorization Code Flow with PKCE works in practice, and how to implement it to enable context-aware tools. This is a hands-on walkthrough for developers looking to integrate model context systems with real-world platforms using standard web technologies.

By the end, you’ll understand how to set up an MCP, walk through the complete authorization lifecycle, and apply these patterns to your own context-fetching services.

📌 **Using WebAssembly to Safely Run Unsafe Code Right on the Client** with Robert Ismo

This talk walks through the process of integrating QuickJS, which targets WebAssembly, into a web application. WebAssembly is a binary instruction format designed as a portable compilation target enabling deployment on the web for client and server applications. QuickJS is a small and embeddable JavaScript engine.

By the end, you'll learn a method of sandboxing untrusted code and how to use it to provide a higher level of customization to end users.

**📌 From Idea to App: Rapid MVP Development in React Native** with Aarón Ramírez Lezama

Learn how to take an idea from zero to MVP with React Native. We’ll set up a project, call a Movies API to fetch and display data, and add navigation — all while covering best practices you can reuse in your own apps.
