He builds maintainable mobile applications using Kotlin Multiplatform, Flutter, and native technologies. He specifically focuses on application architecture, data modeling, and writing reliable tests. His recent talks tackle the complexity of hardware integration, showing developers how to build predictable, cross-platform Bluetooth Low Energy clients. He also researches LLM vulnerabilities and defensive strategies against prompt injection. Based in Munich, Georg lectures on mobile app development at Hochschule Furtwangen. He originally pivoted to mobile software the day the first iPhone broke cover. ## Past Sessions ### World Congress 2026 Europe 路 July 8, 2026 Berlin, Germany - [Building a Cross-Platform BLE Client with Kotlin Multiplatform and Kable](https://www.wearedevelopers.com/videos/100250-building-a-cross-platform-ble-client-with-kotlin-multiplatform-and-kable) 路 30 min 路 馃帴 Watch recording ### World Congress 2024 路 July 17, 2024 Berlin, Germany - [Manipulating The Machine: Prompt Injections And Counter Measures](https://www.wearedevelopers.com/videos/986-manipulating-the-machine-prompt-injections-and-counter-measures) 路 30 min 路 馃帴 Watch recording ## Videos - [Building a Cross-Platform BLE Client with Kotlin Multiplatform and Kable](https://www.wearedevelopers.com/videos/100250-building-a-cross-platform-ble-client-with-kotlin-multiplatform-and-kable) 路 Georg Dresler - [Manipulating The Machine: Prompt Injections And Counter Measures](https://www.wearedevelopers.com/videos/986-manipulating-the-machine-prompt-injections-and-counter-measures) 路 Georg - [Tackling Complexity With Functional Programming And Kotlin](https://www.wearedevelopers.com/videos/705-tackling-complexity-with-functional-programming-and-kotlin) 路 Georg Dresler ## Links - [LinkedIn](https://www.linkedin.com/in/georg-dresler-18b10a119)
