Professional Summary

I’m a Solution Architect and senior .NET developer with over 20 years of experience. My work combines technical leadership with hands-on development, focusing on distributed systems and asynchronous messaging.

Current Role

At Swiss Post, I work with fellow architects to guide development across Logistics Services, primarily in sorting. I work particularly closely with the sorting preparation team, whose applications define sorting plans and support short-term adjustments to changing operational needs.

  • Technical direction: guide developers on technology choices, implementation approaches and API design through reviews, discussions and hands-on support.
  • Planning: work with the Product Owner to set priorities and guide development increments.
  • Integration: support other Logistics Services projects and collaborate with software and hardware suppliers to integrate their solutions into our systems.

Our team owns its services through production operation, using trunk-based development, continuous delivery and automated testing. We review production warnings and errors weekly, addressing issues and reducing log noise, and monitor application performance and resource usage to guide ongoing improvements.

Silverback — .NET messaging library

I’m the author and maintainer of Silverback, a library for asynchronous messaging and event-driven systems with Apache Kafka and MQTT integration.It is the standard messaging solution for all .NET applications at Swiss Post.

Silverback keeps me closely involved in hands-on development, from API design to delivery guarantees, concurrency and integration reliability.
