Field intel

  • INTEL #01LOGGED

    Java → Kotlin, one service at a time

    Null safety, data classes and coroutines without leaving the JVM or Spring. This site is written in Kotlin too.

  • INTEL #02LOGGED

    Event-driven systems that fail well

    Dead-letter queues, idempotent consumers and back-pressure: the unglamorous parts that keep pipelines alive.
