Lead DevOps Engineer
· Sonstige Branche
2023 — heute
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)

2022 — 2024
I was part of the “Tiger Team” or more meaningful: “Performance Team”.
Our customers in the public sector lacked knowledge and visibility into a complex IT landscape.
The Tiger Team created insights, led workshops and provided custom tooling (e.g. Grafana Dashboards) incl. data aggregation and transformation.
Core Responsibilities
- Facilitating communication between development teams and the public-sector client (serving as primary point of contact)
- Designing and implementing a modern observability solution based on Instana
- Modernizing the technology stack within the SDLC (GitLab, DevSecOps)
- Stakeholder management across various public-sector end clients
- Standardizing communication and documentation of business processes (BPMN, DMN)
Key Achievements
- Established a new performance team bridging the gap between customer and public-sector client
- Rolled out APM solutions including Instana, Prometheus, and Grafana within the public-sector organization
- Led workshops on observability topics (situational awareness and alerting systems)
