I’m passionate about cybersecurity, hands-on hacking, and playing CTFs. I’ve even competed twice in the German Cyber Security Challenge—and won with my team! I’m also a big advocate for open source and love contributing whenever I can. Recently, I’ve been diving into mobile app development for Android using Kotlin and Jetpack Compose, adding to my experience in building websites from time to time. Beyond tech, I enjoy outdoor sports, especially mountain biking and hiking, which give me a great balance between digital challenges and real-world adventures.

(November 2023 - ongoing)

wgtwo got acquired by Cisco 🎉

As part of Cisco, our team is aligning with Cisco tools and procedures while expanding our portfolio of Kubernetes controllers. One key development is a controller that enables the dynamic movement of Elastic Network Interfaces (ENIs) across a Kubernetes cluster, allowing us to bring legacy telco protocols and applications to the cloud. Additionally, we’re building tools to streamline the management of multiple clusters, ensuring they remain easy to maintain, debug, and consistent.

Our recent initiatives include:

  • Migrating the knowledge base to Confluence for improved documentation and collaboration.
  • Developing a Kubernetes controller and scheduler to dynamically provision and move ENIs across nodes.
  • Controllers to manage AppDynamics resources
  • Transitioning to OCI artifacts and standardizing Helm charts as the primary deployment method.
  • Strengthening cluster security through artifact signing, Gatekeeper policies, and other hardening measures.

wgtwo

(August 2023 - November 2023)

… as an Infrastructure Engineer. Working on observability, federated metrics and kubernetes.

The Infrastructure team plays a critical role in ensuring the scalability, reliability, and security of our core network and services. We specialize in adapting Kubernetes to support legacy telco protocols, managing CI/CD pipelines and developer tooling, overseeing networking in AWS, and building robust monitoring and observability solutions. Every decision we make is driven by a strong focus on security, efficiency, and developer experience.

Our work includes:

  • Using Terraform to manage Kubernetes clusters, networking, and cloud infrastructure.
  • Operating a range of open-source tools, including Harbor, Dex, OAuth2-Proxy, Grafana, and Prow.
  • Developing and maintaining Bazel rules for Protobuf linting and testing, Helm charts as well as OCI artifact management.
  • Building internal tooling to improve developer workflows and enhance overall productivity.
  • Implementing OpenTelemetry for comprehensive observability and distributed tracing.

By combining automation, security best practices, and a developer-first mindset, we create a solid foundation for scalable and resilient infrastructure.

gridX GmbH

(August 2018 - July 2023)

Started as a junior developer and finished as a Senior Software Engineer. At gridX I was responsible for designing, building, monitoring and deploying APIs for the Web and IoT devices. The stack included event processing and data aggregation which were operated at scale - an indispensable asset to our customers. I’m used to working in a high responsibility environment and finding reliable solutions for the problems at hand. Lately we employed cloud based solutions e.g. AWS Lambda and StepFunctions to manage our workloads and scale effortlessly.

During the time at gridX I built several systems including Authentication, Access Management, Full text search, Event based communications and many more. My final contribution was the extraction of a component from a monolithic service. During this project I planned the required steps in close collaboration with the team and my manager, defined the necessary interfaces, compiled a plan with tangible success indicators for each phase and finally executed the plan with my team.

Incomplete list of technologies I used:

  • Go
  • gRPC
  • Postgres
  • AWS
  • Terraform
  • K8s
