Projekthistorie
I was hired by the General Manager to steer the struggling but commercially successful organization towards a modern technology organization.
The biggest challenge is the success of this company. The digital product is successful but the technological foundation lacks any ability to move. The ability to deliver value, yet even responding to security events is non-existend.
Within two years the goal is to turn the technology organization around.
Core responsibilities
• Building a modern software organization
• Migrating all CI/CD processes to GitHub
• Establishing a DevOps mindset across the technology organization
• Enabling development teams through streamlined processes
• Managing stakeholders in integration and delivery workflows
Key Achievements
• Successfully led the organizational and technical migration of the entire technology organization (50+ projects) from GitLab to GitHub
• Trained staff in workflows and process optimization across the entire software development lifecycle (SDLC)
Tools and technology:
Gitlab (On-Prem), Github.com, GIT, CI/CD, Deployment Automation, SBOM, CycloneDX, Gradle, Maven, Google Cloud Platform, Java 8 to Java 21 (migration), Apache Tomcat, JakartaEE, Wildfly, Ansible, Puppet, Docker, Kubernetes, ArgoCD, SOPS (Secrets Management), Open Telemetry, Datadog APM

As Senior IT-Architect I was part of a migration project from mainframe-based systems to modern Kubernetes based workloads. I was also part of an onboarding effort for bringing Apache Spark into the technology stack which was heavily event-driven (powered by Kafka).
Core Responsibilities
• Designing future-proof technical solutions for decentralized data provisioning, aligned with the selected technology stack (integration architecture)
• Serving as the primary architectural contact within the workstream, supporting both the Product Owner and development teams in defining and implementing user stories
• Providing clear communication to the development team regarding goals, priorities, and domain context, while coordinating actively with domain experts and fellow architects across the program
Key Achievements
• Designed and introduced a phased model for replacing the mainframe-based authorization platform
• Conceptualized, implemented, and taught a data integration solution based on Apache Spark
• Designed and rolled out a CDC (Change Data Capture) solution for streaming data from mainframe systems to a cloud environment
Tools and Technologies
Java 11+ microservices, Cobol, Kubernetes, Prometheus, Grafana, Elasticsearch, Filebeat, Kafka, Apache Spark, Jira, Confluence
Concepts: Domain-Driven Design (DDD), Change Data Capture (CDC), Interface Specification, Agile Project Management
