Ivan Lopez presented on Micronaut, a new Java framework for building microservices. Some key features of Micronaut include being ultra-lightweight and reactive using Netty, ahead of time compilation with no reflection at runtime for improved performance, and native support for cloud-native applications and serverless environments. It also aims to improve developer productivity through features like dependency injection and reflection-free compilation. Lopez demonstrated example Micronaut code and provided several links for learning more about Micronaut.
