At Siemens AG, I held final architecture authority across six teams as Lead Architect and delivered the full annual scope using 85% of the planned budget. I also designed a customer-accepted migration roadmap from Windows Server to Kubernetes with AWS edge-cloud requirements.
As Business Architect at Siemens AG, I established an Architecture Board and ADR process across four products. My portfolio-wide test strategy helped raise average branch coverage from 52% to 85%; the next version had 10% fewer production defects than the previous one.
As Solutions Expert at Siemens AG, I led an Azure-based MES/ERP integration using APIs and Apache Kafka through production acceptance. I also recovered an escalated Oracle ERP/intralogistics project through acceptance in eight weeks, including a wearable-reader integration I implemented to mitigate RFID detection risk.
I'm currently delivering solution architecture for freelance projects in Germany and developing rastr.eu, my published .NET/React product for location reports. I used written specifications and architecture guidelines to direct AI agents, turned five use cases into automated tests, and combined continuous-integration checks with personal code review.
Certified TOGAF Foundation and System Architect @Siemens.
