Hartmut Armbruster is a software architect at StoatFlow who designs high-load distributed systems. He builds mission-critical data platforms for organizations like HSBC and Deutsche Bahn, focusing on architecture that matches actual engineering scale rather than defaulting to maximum complexity.
His work centers on data streaming and reactive programming. He regularly challenges standard operational conventions, whether he is questioning the need to over-scale Kafka and Flink deployments or exploring practical methods to maximize Cassandra performance using Kotlin and Quarkus.
