DevOps / Platform Engineer with 3+ years of experience designing and operating Azure-based platform infrastructure, specializing in AKS, Terraform, Landing Zones and end-to-end infrastructure delivery. Experienced in building reusable platform components, managing multi-subscription environments, and supporting production Kubernetes platforms with strong focus on automation, reliability and security.

DevOps / Platform Engineer at TCG Informatik AG · Thomson Reuters (2023-01 – Present)

• Managed cloud infrastructure across 6+ isolated environments, enabling consistent and repeatable deployments through Infrastructure as Code.
• Designed and maintained parameterized end-to-end Azure DevOps pipelines for full landing zone deployments — allowing operators to select target landing zone and database engine (PostgreSQL or MSSQL) at runtime, then orchestrating Terraform provisioning, Helm-based platform deployment, and Windows container initialization on AKS in a single pipeline with Create/Destroy modes and approval gates.
• Operated a production Kubernetes-based document processing platform across multiple environments, handling Helm deployments, workload troubleshooting and platform reliability improvements.
• Identified and resolved a critical database connection leak that caused repeated service outages, restoring stable operation and preventing future recurrence.
• Completed a security compliance upgrade (TLS enforcement) across cloud services ahead of a strict vendor deadline, with zero service disruption.
• Designed and delivered 6+ production-grade Azure Landing Zones end-to-end with Terraform, covering virtual networking, AKS, Key Vault, PostgreSQL, MSSQL, Storage Accounts, Private Endpoints, DNS, and Azure AD App Registrations. Enabled consistent, repeatable and compliant infrastructure deployments across multiple Azure subscriptions.
• Architected a modular, Git-versioned Terraform library that standardized infrastructure across all environments, reducing new Landing Zone setup time from several days to under 2 hours while eliminating manual configuration errors.
• Actively consumed and extended Terraform modules across all landing zones, including dedicated modules for VNet peering and DNS private link to support hub-spoke network architecture — iterating on interfaces, patching bugs, and evolving modules as platform requirements changed.
• Worked with AWS infrastructure focused on observability, cost optimization and operational support across 80+ Auto Scaling Groups, with hands-on experience in EC2, ASG, CloudWatch, Cost Explorer, IAM, VPC, Route 53, Secrets Manager and OpenSearch.
• Worked with GitHub Actions reusable workflows for multi-repo application build and artifact pipelines, including publishing to JFrog; analyzed and planned migration from static PAT credentials to short-lived OIDC/GATE tokens to meet TR security standards.
• Integrated applications with Datadog for end-to-end observability — configuring dashboards, setting up alerting, and creating synthetic tests to proactively monitor service availability and performance.
• Leveraged Claude Code with MCP integrations (Azure DevOps, Datadog) to automate operational workflows, accelerate incident investigation and reduce time spent on repetitive engineering tasks.
• Resolved a series of pipeline and infrastructure failures — including stuck deployments, broken role assignments, and network misconfigurations — reducing incident resolution time significantly.
• Rebuilt container base images to remediate security vulnerabilities flagged by cloud security tooling, clearing all critical findings.
