Observability & Monitoring
Expertise in building and standardizing end-to-end observability stacks using Prometheus, Grafana, Alertmanager, Loki, Promtail, Elasticsearch/OpenSearch (ELK), Logstash, Kibana, PromQL, and CloudWatch. Reduction of alert noise through signal-focused SLO monitoring and optimized PromQL dashboards.
Cloud & Infrastructure as Code
Hands-on experience with Azure (AKS, ACR, Key Vault) and AWS (EC2, EKS, VPC, IAM, RDS, S3). Provisioning of production-grade infrastructure using Terraform (OpenTofu) and secrets management with HashiCorp Vault.
Containers & Orchestration
Deep knowledge of Docker, Kubernetes, Helm, ArgoCD, kube-rs, and k8sgpt. Deployment and management of containerized workloads at scale, including GitOps workflows and Kubernetes-managed production fleets.
CI/CD & Automation
Proficiency in GitHub Actions, Jenkins, GitLab CI/CD, Ansible, Python, Bash, REGO/OPA for building automated delivery pipelines and infrastructure automation.
Reliability & Security
Application of SRE practices including SLO/SLI definition, incident response, on-call triage, RBAC, NetworkPolicies, image scanning with Trivy and Snyk, and IAM hardening.
AI / ML Integration
Integration of Claude API (Anthropic), OpenAI API, and scikit-learn (Isolation Forest) for AI-driven incident response systems and anomaly detection in infrastructure monitoring.
Networking & Operating Systems
Solid background in MikroTik, Cisco WLAN, TCP/IP, BGP basics, and routing. Administration of Linux systems including Debian, Ubuntu, and CentOS/RHEL.

Projekthistorie
Architected and standardized end-to-end observability stacks (Prometheus, Grafana, ELK/OpenSearch) across client production environments. Reduced alert noise and accelerated MTTR by replacing legacy thresholds with signal-focused SLO monitoring and optimized PromQL dashboards. Engineered structured logging pipelines (Elasticsearch, Logstash, Kibana). Drove SRE adoption across client teams through runbook-driven incident response, on-call triage, and post-incident reviews.
Developed an AI Incident Response System reducing MTTR to ~60 seconds using Alertmanager, FastAPI, Claude API, and Kubernetes SDK. Built an AIOps Anomaly Detector using Isolation Forest to detect infrastructure anomalies 2-3 minutes earlier than threshold-based alerting. Created a Mini IDP (Internal Developer Portal) removing kubectl from developer workflows. Provisioned production-grade AWS infrastructure with modular Terraform and deployed a k3s cluster on EC2.
Maintained ~99.9% uptime across 5,000 network nodes serving 100,000+ subscribers and 300+ B2B clients. Cut mean time-to-identify by over 80% through automated alert aggregation and triage. Reduced fault frequency from daily outages to 1-2 critical incidents per month with Python automation. Eliminated deployment downtime with a blue-green strategy. Led a cross-functional team of 5. Hardened security by migrating secrets to HashiCorp Vault, enforcing PoLP/RBAC, and adding pre-deploy image scanning.
