My technical expertise lies in full-stack (web) engineering and system architecture. I specialize in designing modern distributed architectures, including but not only event- and message-driven systems, microservices, and CQRS patterns. I support clients across the entire software lifecycle: from initial architectural design and requirements analysis to implementation, containerized deployment, automated testing, and distributed monitoring.
During development, I place a high value on clean code, maintainable design and security (OWASP/GDPR compliance).

Projekthistorie
Led a multidisciplinary team of 7 to build an on-premise system bridging a B2B/B2C webshop, Dynamics ERP, lab software, hardware devices and other on-premise APIs. Designed a message-driven system using .NET APIs, React/TypeScript web app, Keycloak for IAM and Traefik for routing. Managed full on-premise deployments with Docker, OpenTofu for CaC and GitLab CI/CD. Implemented advanced monitoring and distributed tracing using OpenTelemetry and SigNoz. Introduced AI coding agent (GPT/Claude) and automated AI code reviews (Qodo) in CI/CD pipelines. Mentored junior/medior developers.
Led the development of a smart logistics platform for pooling load carriers, directing a multidisciplinary team of 9. Built cloud-native message-driven .NET backends, React/TypeScript web app and Keycloak for IAM. Managed full deployments with Terraform and GitLab CI/CD. Utilized AWS ECS, SQS, Lambda, RDS, S3, VPC, Route 53, CloudFront, IAM and CloudWatch.
Promoted to Lead Developer, directing a multidisciplinary team of 5 on a message-driven background processing system. Developed consolidation algorithms to merge sample requests, preventing duplicate testing and saving significant costs for livestock farmers. Built headless .NET APIs (SQL Server) running in Docker containers and secure partner API connections.
