In this session, I’ll explore how AI-powered tooling is transforming large-scale refactoring and codebase migrations, making these complex tasks faster and more efficient. By leveraging tools like Large Language Models (LLMs), static analysis, and refactoring frameworks, we can automate repetitive code transformations, accelerate migration paths, and reduce human error. I’ll share practical examples of how we can migrate legacy systems to modern frameworks, break monolithic architectures into service-based structures, and automate large-scale code changes across thousands of files.

I’ll demonstrate how tools like OpenAI Codex, GitHub Copilot, and fine-tuned models for domain-specific transformations can assist in these processes, while still integrating with traditional migration tools and CI/CD systems. I’ll also cover the importance of developer oversight, highlighting lessons learned from real-world production rollouts and how to balance automation with manual reviews.

By the end of the talk, I want attendees to walk away with a clear understanding of how to use AI to enhance their refactoring and migration workflows, ensuring they can handle large-scale transformations while maintaining code quality, consistency, and governance.

Join Oleksandr as he explores the world of micro frontends and the advantages and disadvantages they offer. During the talk, Oleksandr will provide an overview of the benefits and limitations of micro frontends while showcasing an example of migrating a monolithic app to a modular application in a monorepo with micro frontends. Attendees will gain valuable insights into each stage of the migration process, as well as a better understanding of how micro frontends can offer scalability and flexibility in their own development projects. Don't miss out on this informative and engaging talk!

Join us for an engaging and insightful journey of transitioning a legacy web application with over 1 million users in the finance industry from Webpack to Vite. Discover the steps, challenges, and surprising moments that made this migration both an adventure and a valuable learning experience — including updating Node versions, modernizing npm packages, and unifying a custom homemade design system with a blend of SCSS and Tailwind.

Demander à une IA de refactorer 200 fichiers React, ça consomme des tokens, ça prend du temps, et ça hallucine parfois. Un codemod peut faire la job en quelques secondes, gratuitement, sans se tromper. Mais écrire un codemod, c'est pas évident. Dans ce talk, je vais vous montrer comment vous pouvez utiliser l'IA pour écrire les codemods qui s'occuperont de réaliser le travail de migration.
