Automation Engineers in Germany

• Automated Kubernetes deployments to over 400 customer target environments (Rancher/RKE2) using versioned Helm charts and Argo CD ApplicationSets for daily releases.
• Created self-service customer onboarding based on versioned runbooks, reducing the process from days to hours; coordinated with customer IT teams (AD/LDAP, SMB/DFS, network).
• Migrated selected services to AWS alongside the Open Telekom Cloud platform: provisioned VPC, EC2, and IAM roles with least-privilege policies using Terraform; operated workloads on EC2.
• Set up Keycloak realms and OIDC/SAML clients for product SSO, federated with customers’ Active Directory.
• Set up tenant-specific strongSwan IPsec sidecars on Kubernetes instead of a central transit VM, with keys in HashiCorp Vault: reduced connectivity costs by approximately 80%, with DFS indexing over the tunnel.
• Designed the high-availability migration of the Redis environment to managed OTC DCS; set up alerting and on-call rotations with incident.io by severity, and improved Grafana queries and indexing.

• Ticket automation for smart devices; SharePoint
• Python, JavaScript, Java, Gradle
• CI/CD Git pipeline and secure programming

• Led QA and test automation for a distributed industrial IoT and data-integration platform connecting shop-floor systems with enterprise applications.
• Designed and maintained automated API and UI tests using Playwright, TypeScript, and Python, covering REST APIs, authentication, resource management, integrations, permissions, and end-to-end workflows.
• Tested distributed services, data pipelines, messaging infrastructure, containerized applications, and integrations across Kubernetes, OpenShift, Docker, and Docker Compose environments.
• Performed functional, integration, regression, endurance, resilience, load, chaos, and exploratory testing across complex distributed systems.
• Used Chaos Mesh and Toxiproxy for network fault injection, latency, packet loss, and partition scenarios to validate system resilience and failure handling.
• Automated infrastructure provisioning, configuration, and environment setup with Ansible and managed deployments using Kubernetes and Helm.
• Tested integrations with industrial protocols, messaging systems, databases, HTTP/REST APIs, and external enterprise systems using simulators, emulators, and dedicated test environments.
• Worked with MQTT, Kafka, SQL databases, InfluxDB, REST APIs, OAuth 2.0, JWT, LDAP, Active Directory, OpenLDAP, mTLS, TLS, MFA, SSO, and RBAC.
• Investigated and resolved 40+ defects across backend services, integrations, distributed components, and web applications, using AI-assisted analysis with Claude to accelerate debugging, test design, and root-cause investigation.
• Improved deployment reliability through Kubernetes/OpenShift configuration and health-check tuning and monitored distributed systems using Grafana, Prometheus, and Loki.
• Collaborated with developers and product teams on sprint planning, technical refinement, quality strategy, release testing, and continuous improvement.
• Applied AI-assisted and agentic testing approaches to expand automated coverage and identify complex edge cases.

Industry Software from Route to Invoice

In Production

In use at: landscaping company, two home care services

The entire workday, digital: sign-in, route plan on the vehicle, departure checks, photo documentation, time tracking, invoicing. The tablets keep working offline and sync afterward. Records are immutable, making time tracking easier to audit. Runs on a dedicated server in Germany with continuous monitoring and remote updates.

Proof: In daily use at the landscaping company with six vehicles since September 7, 2026.
