Summary
I design and implement robust, secure, and highly automated cloud infrastructures that enable companies to accelerate their software development and bring innovations to market faster. I see myself as a strategic partner who translates technical excellence into measurable business success.
My expertise focuses on three core areas:
- Migration & Modernization: I transition monolithic on-premise systems to scalable, cloud-native architectures (Kubernetes, Microservices), thereby sustainably reducing technical debt and operational costs.
- Security & Compliance: I implement "Security by Design" principles throughout the entire cloud infrastructure and ensure compliance with industry standards and regulatory requirements.
- Automation & Efficiency: By introducing GitOps, IaC, and comprehensive observability, I increase the efficiency of development teams, minimize manual errors, and significantly reduce the mean time to repair (MTTR).
My goal is to act as a strategic partner for companies that want to increase their innovative strength through the use of modern technologies. I translate complex technical requirements into stable, secure, and scalable cloudnative solutions, thereby creating the foundation on which agile teams can develop their products with the highest quality and speed.
