Senior Site Reliability Engineer

I am the sole SRE responsible for the reliability lifecycle of three STACKIT SaaS products: Forgejo-based Git hosting, Kubernetes-based CI Runners, and a Harbor-based Container Registry serving thousands of tenants. I defined the product-wide SLO/SLI model, alerting strategy, synthetic monitoring with CanaryChecker, and Grafana dashboards powered by Prometheus and Thanos.

I standardized GitOps practices and reproducible delivery workflows, reducing deployment time from one hour to under five minutes. I act as Incident Commander and primary on-call for major production failures, lead postmortems, partner with the Product Owner on reliability priorities, influence architecture with Tech Leads, and coordinate cross-team reliability requirements as a Reliability Working Group Ambassador.

I originally built a fully self-hosted, auto-scaling platform on Hetzner as the sole DevOps engineer. The platform was subsequently replicated across multiple internal projects.

I implemented observability with Prometheus, Tempo, and Loki for end-to-end traceability and proactive monitoring. I designed CI/CD pipelines with Gitea and GitHub Actions, reducing deployment time by 60% while supporting automated rollback; I continue to provide part-time technical guidance on platform reliability and GitOps workflows.

I architected Kubernetes clusters on GKE using Terraform, Terragrunt, and GitOps with Argo CD. I also designed GitLab CI/CD pipelines that eliminated manual deployments and reduced configuration drift risk.

I improved infrastructure delivery performance by reducing Terraform execution time by 60% across three environments. I optimized pre-production workloads by removing unused Istio components, reducing memory usage by 30%.

I automated deployments and observability for more than 400 servers in a hybrid video-analytics platform. My work improved operational consistency and visibility across a large server estate.

I created health probes that reduced manual evaluation effort from four weeks to under four hours. I also developed infrastructure-as-code automation with Ansible and Python for consistent node bootstrapping.

I delivered AKS-based cloud-native environments and containerized applications on Azure. I supported the deployment and operation of cloud-native workloads using standardized platform practices.

I created reusable Terraform modules that minimized infrastructure drift and deployment errors. I also built CI/CD pipelines for microservices, increasing deployment frequency.

I implemented CI/CD pipelines in Azure DevOps for .NET and SQL Server applications. I supported reliable software delivery for production application workloads.

I resolved production outages caused by memory saturation by tuning autoscaling behavior and resource limits. I managed Azure resources with ARM templates and supported cost modeling for database workloads.

I managed Azure infrastructure, including virtual networks, storage, and resource groups. I automated provisioning pipelines to improve consistency and repeatability across infrastructure operations.

I automated patch management and compliance enforcement using SCCM and PowerShell. This work supported secure and standardized enterprise systems operations.

At UPC, I provided IT support focused on Windows and network troubleshooting, achieving an 85% first-contact resolution rate. I supported users by diagnosing and resolving common technical issues efficiently.

At Lifebits.ai, I worked as a Web Design Intern and assisted with responsive UI development. This role provided early experience in web development and user-interface implementation.

Specialized in the Computer Science track.

Completed a semester abroad focused on distributed systems and cloud-native architecture.
