I am a passionate Site Reliability Engineer with deep expertise in infrastructure automation, service integration and observability. Over the years, I’ve specialized in building scalable, secure and self-service platforms, with a strong focus on Kubernetes-based operations and cloud-native design. My experience ranges from migrating complex legacy systems into modern Kubernetes environments to designing high-performance cloud platforms that integrate advanced networking, distributed services and automation at scale. I have led projects where I collaborated with developers, DevOps teams and operations staff to establish modern practices, improve delivery velocity and ensure reliability across environments.
I thrive in designing and implementing solutions such as:
I thrive in designing and implementing solutions such as:
- Kubernetes clusters and multi-cluster management operators.
- CI/CD pipelines with Helm, GitLab, ArgoCD, and Flux.
- Observability stacks (Prometheus, Grafana, OpenTelemetry, VictoriaMetrics) with white-box monitoring, metrics, alerts, and dashboards.
- Cloud and virtualization platforms (AWS, GCP, OpenStack, VMware, bare metal).
- Secure and reliable services including S3 storage, PostgreSQL, Redis, and messaging systems like NATS.

Projekthistorie
- Guided development teams on cloud-native design patterns and best practices to ensure seamless Kubernetes integration.
- Designed and deployed Helm charts and CI/CD pipelines to support reproducible, scalable and automated deployments.
- Designed and optimized Kubernetes workload deployments to ensure high availability, resilience and reliability across zones.
- Configured and rolled out a white-box monitoring system (metrics, alerts, dashboards) to provide deep visibility and ensure system reliability.
- Collaborated cross-functionally with developers, DevOps engineers and operations staff to establish modern DevOps practices and improve delivery velocity.
- Designed and prototyped a high-performance, hyperconverged Kubernetes platform for bare-metal infrastructure, featuring advanced BGP-based networking to facilitate efficient distributed deployments and the creation of CRDs along with the implementation of an operator for multi-cluster management.
- Designed a dedicated service cluster layer to expose fully managed services—including S3-compatible object storage, PostgreSQL, Redis and others, available to tenant workloads through standardized APIs.
- Developing core features such as IAM, RBAC, audit logging and self-service interfaces, built on an API-first architecture to enable full automation and extensibility.
- This includes infrastructure migration, automation and service optimization. A key part of this involved porting the proprietary Golang provider implementation to OpenStack to facilitate resource provisioning and management.
