### “Retrieval-Augmented Generation in Practice”, by Sergei Muravskii, Senior Frontend Developer at Devexperts

About the Talk
In this talk, we explore the root causes behind early AI limitations and how retrieval-augmented generation (RAG) helps overcome them. Using Cursor as a real-world case study, we examine repository-level context, abstract syntax tree chunking, and other RAG-driven agent workflows.
We conclude with practical, evidence-based guidance on verification, privacy, and responsible adoption for engineering teams.

### “How to Put your App on a Diet - Frontend Performance Playbook”, by Xavier Costa, Junior Frontend Engineer at Uphold

About the Talk
Your users leave faster than your app loads, and it's definitely not Backend's fault. Let's fix that, using a real webpack-to-vite migration at a crypto exchange as an example and a cross-platform performance playbook that makes your users stay:
- For the web: bundle analysis, image optimization, lazy loading, and SSR vs CSR.
- For mobile: keeping the JS-to-Native communication lean, offloading animations to the UI thread, efficient list rendering, and rapid state management.
Two platforms, one playbook, exponential performance improvements.
