AWS Cloud Infrastructure
Extensive expertise in designing, building, and managing AWS cloud infrastructure including VPC, EC2, ECS, ECR, Lambda, RDS, CI/CD, SNS, SQS, SSM, Route53, CloudFront, S3, and WAF. Proven track record of delivering scalable, highly available, and cost-optimized cloud environments across multiple production projects.
Infrastructure as Code mit Terraform
Deep hands-on experience with Terraform for automating cloud infrastructure provisioning across AWS and Azure. Expertise includes designing reusable Terraform modules, implementing best practices for naming conventions and module structure, semantic versioning, and building CI/CD pipelines for automated Terraform validation, planning, and deployments.
Container-Orchestrierung mit Kubernetes und Docker
Strong background in containerizing applications using Docker and orchestrating workloads with Kubernetes and AWS ECS. Experience includes building snapshot-based Kubernetes simulation environments, managing ECS Fargate workloads, implementing service mesh stacks, and designing CI/CD pipelines with ArgoCD, Gitea, and Harbor for polyglot microservices platforms.
CI/CD Pipeline Engineering
Comprehensive experience designing and maintaining CI/CD pipelines using AWS CodePipeline, CodeBuild, CodeDeploy, Bitbucket Pipelines, GitHub Actions, and GitLab. Includes automated build, test, deployment workflows, QA and stress/load testing automation, and GitOps-based delivery with ArgoCD.
Monitoring und Observability
Practical experience implementing centralized observability solutions using Datadog, Grafana, Prometheus, Loki, Jaeger, and OpenTelemetry. Includes log streaming with Logstash and Elasticsearch, monitoring Amazon RDS and ECS containers, and setting up alerting rules such as PrometheusRule for proactive incident detection.
Backend-Entwicklung mit Node.js und Python
Solid software engineering background building scalable backend services and REST APIs using Node.js, Python, and FastAPI. Experience includes developing microservices architectures with Serverless Framework, real-time services with Socket.IO, and custom ETL-style data ingestion workflows.
Azure Cloud und Multi-Cloud-Umgebungen
Hands-on experience with Microsoft Azure including Virtual Networks (VNet), Subnets, Azure Functions, Azure Data Factory, and Azure PostgreSQL. Contributed to infrastructure development, automation, and data pipeline design for copying and transforming data from Amazon S3 to Azure PostgreSQL.
Sicherheit und Zugriffskontrolle
Experience implementing security measures including AWS WAF with rate limiting and Managed Rules, Keycloak and Authentik SSO with OIDC/OAuth2, RBAC groups, and scoped token policies. Includes securing access to Grafana and ArgoCD and enforcing immutable production tag policies in Harbor.

Project history
Engineered and maintained Nebula, a snapshot-based Kubernetes simulation environment achieving 60-second full-cluster boot times for a 60+ pod, 15-namespace k3s cluster with complete CI/CD, observability, and service mesh stacks. Designed and authored hands-on DevOps incident scenarios covering container registry corruption, database split-brain recovery, clock-skew-induced object storage failures, and timeline service outages. Modernized a GitOps CD pipeline by integrating ArgoCD Image Updater. Built end-to-end CI/CD pipelines from scratch using Gitea, Harbor, and ArgoCD for a polyglot microservices platform. Deployed Authentik SSO with OIDC/OAuth2. Diagnosed and resolved a MinIO presigned URL failure caused by NTP clock skew. Resolved a critical multi-architecture manifest corruption incident in Harbor. Recovered a PostgreSQL split-brain in a live Kubernetes environment. Fixed Keycloak realm misconfiguration blocking SSO login for all platform users.
Designed and built cloud infrastructure from scratch using Infrastructure as Code for a production product across multiple AWS services. Established versioning and release automation using semantic-release. Led development of HR integration feeds, designing end-to-end data ingestion workflows. Built custom ETL-style services using Node.js. Architected and implemented data processing flows using AWS Lambda, then migrated to ECS Fargate. Improved scalability and reliability of data pipelines by adopting containerized, task-based processing on ECS Fargate.
Built scalable AWS ECS infrastructure using Terraform. Created CI/CD pipelines with AWS CodePipeline, CodeBuild, and CodeDeploy. Developed backend REST APIs and real-time services using Node.js and Socket.IO. Built frontend applications using React.js and Redux. Designed and developed notifications and messaging microservices using SocketIO and Node.js. Established Git-based development workflows and best practices.
