Summary

I am a Cloud Architect and Infrastructure Automation Specialist with over 25 years of experience in system engineering and IT operations.

My core focus lies in the integration and migration of complex cloud environments (OCI, AWS) and the development of scalable automation solutions using the HashiCorp toolstack (Terraform, Vault, Consul, Nomad, Packer) as well as the Red Hat Ansible Automation Platform.

I support organizations in transitioning from traditional IT infrastructures to dynamic, agile cloud architectures and in modernizing internal workflows. In addition to deep technical expertise, I bring long-standing experience in leading critical transformation projects in regulated and high-security environments.

In the field of AI, I design and provide private infrastructure for training and fine-tuning proprietary LLMs and RAG systems, both in the cloud and on-premises.
