Why attend in 2027?

Code Review at Agent Scale Workshop Included

AI agents now write a lot of the code teams ship, but most people still review it like code from a colleague. Agents repeat the same mistakes, don’t know your system, and write code that usually looks right even when it isn’t. In this workshop, attendees build a set of review skills for their own AI agent. Each skill checks for one kind of problem. The idea: build a toolkit you can use every time you review.

JavaScript in the age of AI

Learn how modern engineering teams use AI to build, test, debug, deploy and operate JavaScript applications. Explore AI-assisted development, TypeScript at scale, agentic workflows, browser APIs, edge runtimes, WebAssembly, performance, architecture, observability and security—all designed for senior JavaScript engineers.

The Next Decade of JavaScript

What should you invest in? The AI Transition? How will your job look like in the future? Hear it from Framework creators, browser engineers, tooling experts, and developer educators.

    Luca Mezzalira

    Director @ 50 cents media

    🎤 Building an agentic harness for your projects | Luca has spent 20+ years helping engineering organisations design distributed systems that scale, not just technically, but organisationally. Architecture isn't only about technology; it's about enabling teams to move faster, make better decisions, and build software that lasts. At DAZN, as VP of Architecture, he led the transformation towards microservices and micro-frontends at streaming scale, helping reshape how engineering teams delivered software across the organisation. At AWS, he partnered with some of the world's largest organisations as a Principal Solutions Architect, leading the EMEA go-to-market strategy for serverless, delivering keynote and breakout sessions at re:Invent, and facilitating architecture workshops, Event Storming sessions, and distributed systems design across industries including retail, finance, media, travel, healthcare, energy, insurance, and the public sector. He spent years turning micro-frontends from a nascent idea into an established architectural discipline through research, experimentation, open source, and the O'Reilly book that has become a reference for engineering teams modernising their front-end architectures. He has helped hundreds of organisations worldwide design and scale modern web applications using these principles. Today, his research focuses on how AI is reshaping software architecture: from engineering workflows and software design to the evolving role of architects in an AI-native world.
