📱 Mobile Warsaw #107 — Engineering Culture, Team Scaling & Agent Skills
Three talks, three different perspectives, one shared theme: how mobile teams can work better as they scale, hire, and adapt to the new AI-powered reality. During Mobile Warsaw #107, we’ll look at engineering culture, team structures, and practical ways of extending AI agents beyond simple prompting.

🕗 EVENT AGENDA
18:30 — Introduction & Welcome
Welcome to Mobile Warsaw #107! Community announcements, and a brief overview of tonight's talks and networking opportunities.
18:40 — Scaling team without scaling chaos [Sponsored talk]
Jakub Kornatowski
By day, a problem solver with more ideas than hours and an engineer building apps for anything with an apple in the logo at XTB. By night, a gamer - 25 years in, 12 of them almost exclusively on Mac, which tells you everything you need to know. Occasional reverse engineer, part-time 3D triangle pusher on Apple Silicon. Creator of the "Gramy na Macu" podcast. When not at his desk, you'll find him on one of Kraków's climbing walls.
What happens when 35 engineers, 20 teams, and one shared codebase meet without clear rules?
Spoiler: you get a bug on production, a hotfix at midnight, and a very expensive lesson about conversations that never happened.
Come hear how we built the structure that made the chaos survivable - and why it matters even more now that AI is writing your code.
19:20 — Break & Networking
As usually during the break you can find a warm pizza waiting for you, beverages are available all the time in the kitchen!
19:45 — Engineering Culture by Design: jak i dlaczego cisnę kandydatów jako techlead (This talk is hosted in Polish 🇵🇱)
Paweł Urban & Jaga Biernacka-Urban
Senior Android developer z ponad 16-letnim doświadczeniem zdobytym w fintechu, startupach i IoT. Staff Engineer z silnym backgroundem w architekturze i niezawodności systemów, praktyk DDD i mentor techniczny. Wielokrotnie prowadził rekrutację do swoich i nowo powstających zespołów. Wierzy, że poprzez dzielenie się wiedzą, pracę przykładem i wspólne praktykowanie można osiągnąć doskonałość inżynierską w skali całej organizacji.
Psycholog społeczny z backgroundem technicznym, badaczka i wykładowczyni akademicka. Od lat współpracuje z organizacjami technologicznymi, wspierając liderów i zespoły w budowaniu współpracy oraz adaptacyjności. Specjalizuje się w tworzeniu uczących się organizacji i pomaga liderom projektować zarządzanie wiedzą i budowę kultury inżynierskiej.
W tym wystąpieniu pokażemy, jak techlead może testować kandydatów, by sprawdzić ich wiedzę techniczną, podejście do rozwiązywania problemów i orientację zespołową – zanim dołączą do zespołu. Pokażemy konkretne pytania, zadania i ćwiczenia, których używamy podczas technicznej części rekrutacji.
Zrobimy to na przykładzie Androida, ale każdy będzie mógł łatwo przełożyć przykłady na swój obszar.
To praktyczny przewodnik, jak projektować silną kulturę inżynierską i zdrowy mindset zespołowy już na etapie zatrudniania. Będziemy mówić o zatrudnianiu w różnych kontekstach - utrzymania dobrej kultury lub naprawieniu słabej. Pokażemy też, jak wyłapać trudne “osobowości”, jak testować postawy kandydatów i ich nastawienie do współpracy. Wszystko to oparte o nasze doświadczenie i realne casy.
20:30 — Beyond Prompts: Extending Agents with Skills [Sponsored talk]
Łukasz Domaradzki
If AI is going to write more of our code, how can we teach it our team’s rules, workflows, and architecture patterns without stuffing everything into giant prompts?
Agent Skills turn specialized knowledge, tools, and repeatable workflows into modular capabilities that agents load on demand.
In this talk, we’ll explore what Skills are, why they matter for mobile teams, and how to start building your own - with practical demos, real examples, and a small dose of pop culture included.
