DevFest Wrocław 2025

Get ready for the biggest community-driven tech event of the year! GDG Wrocław is proud to host DevFest Wrocław 2025, a part of the global conference series that brings together passionate developers to explore the latest in developer tools and connect with peers.

This year, our theme is "Building Safe, Secure and Scalable Solutions with AI and Cloud." We'll focus on the practical integration of AI and Google Cloud to equip you with the skills needed to build innovative, scalable, and ethically sound applications that will shape our technology-driven future.

Our agenda is packed with deep-dive sessions from industry experts. You'll learn how to build resilient, crash-proof Android apps using principles from safety-critical systems, discover how to supercharge your workflow by connecting AI agents directly to Chrome DevTools, and take a deep dive into the inner workings of the Jetpack Compose compiler and runtime.

Join us for an evening of deep technical knowledge, networking, and community building. We can't wait to see you there!

Agenda

6:00 PM: Beyond Exceptions: Building Resilient Android - Bogusz Pawłowski

Apps with Safety-Critical Principles

When your Android app crashes, users uninstall. This session explores how to handle failures before they become crashes, focusing on Android's unique reliability challenges.

We'll establish the critical distinction between domain errors (expected business logic failures) and system failures (unrecoverable hardware/OS issues), implementing each with appropriate strategies. You'll learn to build a custom Result monad that provides compile-time safety beyond Kotlin's built-in limitations, and we'll see how NASA's mission-critical safety rules can be applied in the Android world. You'll also master native crash debugging techniques for those unavoidable system failures.

From handling hardware state corruption to graceful degradation under memory pressure, you'll walk away with battle-tested patterns for Android's trickiest reliability scenarios: complex state management, native code integration, and building apps that degrade gracefully rather than crash catastrophically.

7:00 PM: AI Meets Chrome: Supercharging Development with DevTools MCP - Adrian Romański

Ever wondered what happens when you give your AI coding agent the full power of Chrome DevTools?

In this session, we’ll explore Chrome DevTools MCP, a Model Context Protocol (MCP) server that bridges your AI assistant (Gemini, Claude, Copilot, etc.) with a live Chrome instance.

We’ll see how this unlocks new workflows:

• Automating clicks, form fills, and navigation
• Capturing performance traces and extracting insights
• Debugging with network requests, console logs, and screenshots
• Emulating conditions like CPU slowdown or network throttling

You’ll leave with practical knowledge and examples to start experimenting with AI-driven debugging, automation, and interactive web development - powered by Chrome.

8:00 PM: Compose Deep Dive - Wolfram Rittmeyer

Jetpack Compose is great - and no one want to return to the

old view based system. But how does it actually work? Which role plays

the compiler plugin? How does it change our code?

And what about the runtime? Where is the actual drawing taking place?

Who triggers recompositions? And how does this differ depending on

whether you use Compose on Android or Compose Multiplatform?

You will get insights into the Compose Compiler and Runtime that help

you understand better how Jetpack Compose and Compose Multiplatform work.
