Profile
I’m a cool coffee interested full stack developer with 10+ years experience. Besides that I move freely in the stack from JVM languages (such as Scala, Java and Kotlin) to Go, typescript, UX, database design, kafka, architect and mentor roles. I like to fish with nets and brew coffee in my off time and play chess.
