At DekaBank, I was the solution architect for S-Invest Manager, a cloud-based securities sales and advisory platform developed with Cofinpro. I guided the architects of five development teams and was responsible for the platform-wide DevSecOps architecture and continuous-delivery pipeline.
At Ericsson, I led architecture work moving Ericsson Billing and Charging and Billing Evolved toward cloud-native deployment on Docker and Kubernetes, designed for any CNCF platform. I also served as Product Owner and Architect for release verification pipelines on a BSS platform designed to support 500M+ subscribers, and earlier worked hands-on in Linux administration and customer escalations.
