David Blanc

After working as a Java engineer for 8 years in various French IT companies, I moved to mobile application development on iOS and Android in 2012. In 2015, I decided to focus on Android and joined i-BP, an IT department of the French banking group BPCE, as Android expert. I am now passionate about Android, clean code, and, of course, Kotlin programming.
