Java Software Engineer & Cloud Architect – I strengthen your project with expertise that is scalable.
Are you looking for an experienced Java freelancer who can robustly implement complex backend systems, build modern cloud infrastructures on AWS or GCP – while adhering to your security and quality standards? I support you 100% remotely with over 15 years of experience in Java development and many years of cloud expertise.
What I offer you:
- Results instead of experiments: I deliver production-ready software and well-thought-outcloud architectures– from analysis to operation.
- **Java & Spring Boot**: Well-founded from Java 1.2 to 17, with a focus on maintainable REST APIs, messaging architectures, container platforms and security aspects.
- **AWS / GCP / Kubernetes**: Building infrastructure with Terraform, securing it with IAM/KMS/WAF, CI/CD with GitLab. Cloud-native development with a focus on scalability and security.
- **Project References**: I have successfully implemented solutions for well-known customers such as DB Systel, Porsche, PreHCM and Fidelity – often under regulatory requirements and with direct customer satisfaction as a benchmark.
Typical projects that I take on:
- Building security-critical microservice architectures on AWS
- Migration and modernization of Java monoliths into scalable cloud environments
- Connection of external systems (Panorama, Azure AD, Deutsche Post Video-Legitimation)
- End-to-End DevOps Pipelines with GitLab CI, Helm, Kubernetes
- Event-driven systems (e.g. with ActiveMQ, SQS, EventBridge)
What makes me special:
I bring not only technical know-how, but also a feel for your deadlines, security requirements and stakeholders.
My way of working is clear, reliable and hands-on. I think in solutions – not in technology for its own sake.
Ready for your remote project – please contact me.
