🕗 AGENDA
18:50 — Introduction Keynote

19:00 — Mateusz Bartkowiak: Why Do We Need Another Architectural Pattern?

You build apps using MVC, MVP, MVVM — maybe even MVI — but over time everything starts to get messy. Logic leaks across layers, impossible states appear, and debugging turns into a nightmare.
Together, we’ll trace the evolution of architectural patterns, look at where they fall short, and explore how the Finite State Machine (FSM) approach brings order and predictability. Through practical examples, I’ll show how explicit states and transitions simplify logic, limit side effects, and significantly reduce the number of edge cases.
No unnecessary theory — just concrete comparisons, real code, and clear architectural takeaways. You’ll leave the talk knowing when it’s worth reaching for FSM and how it can help stabilize growing Android projects.

Bio: Android Developer at XTB with a passion for exploring new patterns, frameworks, and libraries. A former semi-professional League of Legends player, he brings strategic thinking and strong engagement into his work. Privately a coffee enthusiast, juggler, husband, father, and a proud adoptive dog dad.

19:45 — Break
Enjoy P I Z Z A!

20:15 — Bartek Legięć: TBA
Lightning Talk

Bio: I have been programming in JavaScript for over 10 years now, and these days I mainly focus on frontend development — both during the day at Craft; and during the night working on various sideprojects. However, I have always had an interest in dabbling in full-stack work and design on the side.
Teaching and sharing knowledge is something I absolutely love, and it extends beyond just programming. I enjoy learning new things and passing on that knowledge to others.
