Kotlin and Spring logos
Putting the final touches on my upcoming @springio.net and @kotlinconf.com talk "Idiomatic Kotlin applications with Spring Boot 4" where I will share all my guidelines for build, logging, observability, persistence, etc.
Should be useful both for human developers and agentic engineering workflows.
Cool to read how @springio.net has real-world impact: medium.com/graalvm/insi...
