  • 17engineers in the largest team led — from hiring to engineering practices
  • ESB → EDAintegration modernization with governance and developer self-service
  1. Event-driven design

    Target pictures, service boundaries and domain events as the contract between teams — DDD, Arc42, AsyncAPI.

  2. Business event bus

    A governed backbone: schema registry, versioning, ACLs, ownership and a developer portal for self-service.

  3. High-volume Kafka

    Kafka Streams, error handling, replay and observability on Kubernetes — plus hands-on Kafka training for your teams.

  4. Transaction enrichment

    Categorize transactions, label business events and enrich them with master data on the fly — in-stream, before they reach downstream systems.
