About Me

My focus is on empowering teams and businesses through technology. With a solid background in DevOps and infrastructure, I currently specialize in designing scalable, AI-driven solutions. Recent initiatives include modernizing support workflows by implementing bots for first-level support, significantly reducing operational overhead.

I describe myself as “full-stack curious.” Spare time is often spent on hardware hacking, building smart home setups, and experimenting with Large Language Models. This hands-on experience provides a comprehensive understanding of the technical landscape, from hardware to high-level application logic. I thrive in customer-facing roles, translating technical complexity into practical business value.

Work Experience

  1. DevOps Specialist

    Present

    Atos Information Technology GmbH Berlin, DE, remote

    The DevOps Team for Project “AuRegis” is responsible for the development and operation of a digitized nationwide trade register. Key responsibilities included managing the release process, supporting the microservices architecture on Kubernetes/OpenShift, and overseeing the CI/CD pipelines.

    A major focus was constructing the CI/CD stack from the ground up. Using GitLab CI and Jenkins, essential components such as integration tests, dependency checks, and security scans were integrated. The deployment process to OpenShift/K8S was fully automated via Kustomize and Jenkins/Python Scripts, while SonarQube was established for code quality analysis. Additionally, GitOps workflows were implemented using ArgoCD to manage resources across both Azure and private cloud environments.

    Beyond infrastructure, I actively identified and addressed architectural and code-level improvements to enhance system stability and maintainability.

    Automation within Jenkins was significantly improved through custom Python scripts, Terraform/Ansible, handling tasks like cryptostore configuration and system packaging for all our deliverables within this project. This streamlined the release process for both customer deliveries and test system deployments. For microservices, Kustomize manifests (Helm) and automation scripts were developed, ensuring documentation was treated as code for clarity and reproducibility.

    During the project’s first go-live and going forward, I served as a technical advisor to ensure a smooth launch, later transitioning into the role of Technical Rollout Manager to oversee further deployments.

    Technology Stack:

    • Products: Java, Spring Boot, React, Oracle, MS SQL, Redis, Elasticsearch, RabbitMQ, Python
    • Infrastructure: Jenkins, Azure, OpenShift/Kubernetes, Docker, Kustomize, ArgoCD, Grafana, Prometheus
  2. DevOps Specialist

    Atos Information Technology GmbH Berlin, DE

    For Project “ISBJ-ZVK-UVK”, the objective was to develop and launch a 3-layer application for managing the Berlin Senate’s Advance Child Support Fund. Responsibilities included building the backend using Kotlin and GraphQL, ensuring the solution met specific project requirements.

    In addition to development, the role encompassed DevOps and cloud infrastructure tasks. A CI/CD pipeline was established to deploy the application to an OpenShift environment, which included the configuration of a Keycloak instance and Oracle DB.

    Acting as the technical interface for the client, I managed technical coordination to ensure requirements were clearly understood and implemented, balancing hands-on development with project management duties. Following the successful first go-live, where I served as a technical advisor, I assumed the role of Technical Rollout Manager to lead subsequent deployments.

  3. Corporate student

    Atos Information Technology GmbH Berlin, DE

    During my three years as a Corporate Student at Atos, I studied Computer Science (Informationstechnik) while gaining practical experience, allowing for the direct application of university concepts to real-world projects.

    My engagement with technology extends beyond professional boundaries. A strong background in electronics and software has led to various hands-on projects, such as building and maintaining home servers, 3D printing, and component-level electronics repair.

    This curiosity drives a continuous learning process. There is a strong focus on exploring new technologies and automating processes, with recent interests including Flutter+Dart, Golang, and Python Flask.
