ING Tech Hangouts 
Kotlin for Java developers

ING Tech Hangouts makes an eager comeback for its 4th edition and marks a first-time presence in two cities: Cluj (September 20) and Bucharest (September 21), with Hadi Hariri taking centre stage to break down Kotlin for Java developers.

The forward-looking keynote on Kotlin's place in the future of Java developers demystifies silver bullets and restores faith in the writing process: there are no magic tricks, no magic frameworks, no magic languages. Clean. Your. Code. – building and using quality code never fails. The big questions Hadi Hariri will dive into are Why Kotlin, How to integrate it and What place does it hold in the future of Java developers?

Our colleagues, experienced developers Bogdan Arvinte and Mihaita Tinta, open with Going password-less with Web Authentication. An engaging talk about password vulnerability, explainers, and demo on phishing, damage control in case of data breaches, secure second-factor login with no 3rd party apps, biometric-based authentication with open web standards.
