01 / EXPERTISE

From bare metal
to the cloud.

I connect infrastructure, operations, and product thinking — always keeping reliability, maintainability, and cost in view.

☁

AWS Architecture

Designing secure, scalable environments with EC2, ECS, EKS, Lambda, CloudFormation, IAM, Route 53, CloudFront, and managed data services.

Infrastructure as code
Event-driven systems
Cost-aware design

⌘

Systems Engineering

Linux, networking, DNS, Apache, TLS, VMware, storage, and the operational discipline learned from production systems.

◉

Observability

Monitoring and dashboards with Checkmk, Nagios, Zabbix, Grafana, Prometheus, ELK, and CloudWatch.

⟳

Automation

Ansible, Puppet, Python, GitLab CI/CD, AWS Lambda, EventBridge, and repeatable deployment workflows.

◇

Technical Leadership

Team leadership, project delivery, architecture guidance, knowledge sharing, and communication in German and English.

02 / SELECTED IMPACT

Systems that hold up
when it matters.

PERFORMANCE · RESILIENCE

Introduced Akamai CDN

Connected WetterOnline with Akamai and ran the caching layer for years, offloading up to 90% of requests while improving resilience during severe-weather traffic peaks.

PLATFORM MODERNIZATION

Bare metal to virtualization

Led the move from racks of physical servers to VMware, creating flexibility, reducing idle capacity, and preparing the organization for its later cloud journey.

OBSERVABILITY

Built the monitoring practice

Introduced Nagios through an informatics thesis, later complementing it with Zabbix, Checkmk, Grafana, and cloud-native monitoring.

03 / EDUCATION

Science meets
systems thinking.

Two disciplines shaped the way I approach complex problems: understanding dynamic systems and building dependable technical ones.
