On-premises → AWS migration
A large migration project using Terraform and Ansible to standardize provisioning and configuration.
Senior Infrastructure & Systems Engineer
I build and operate infrastructure that should work predictably.
I combine systems administration, automation, cloud, networking and operations. From complete business environments to enterprise platforms and large migrations — with an emphasis on repeatability, documentation and ownership of the outcome.

Selected highlights
Scale and ownership, not just a list of technologies.
A few examples that best represent my work across production environments and infrastructure projects.
Enterprise Big Data
Administration of HPE Ezmeral / MapR and Cloudera platforms with Hadoop, YARN, Spark and Oozie workloads.
Ansible framework
Reusable roles, structured inventories, environment-specific variables and standardized playbooks for contact-center deployments.
Complete IT environment
Built and operated infrastructure for a licensed casino: networks, servers, endpoints, IAM, backup, monitoring and business-critical systems.
Professional profile
Technology is a tool. The goal is to deliver change without chaos.
I work best where an existing environment needs to be understood, root causes need to be found, and the resulting solution has to remain maintainable after the project is over. My work spans operating systems and networking as well as automation, cloud and data platforms.
In practice, that means fewer one-off “magic” commands and more infrastructure as code, repeatable deployments, monitoring, controlled change and documentation that the next engineer can actually use.

Core expertise
A broad infrastructure profile without being locked into one tool.
I choose technology to fit the problem and the existing environment instead of rebuilding an environment just to match a preferred stack.
Linux & Windows
Systems administration, Active Directory, troubleshooting, updates, hardening and production operations.
Automation & IaC
Repeatable deployments and operations with an emphasis on readability, idempotency and maintainability.
Cloud & Containers
Infrastructure migration and operations across AWS, Azure and OCI, plus containerization and orchestration.
Big Data
Long-term administration of enterprise data platforms and Hadoop ecosystem components.
Networks & Access
TCP/IP, routing, VPN, BGP, IPv6 and hands-on troubleshooting across systems and networks.
Operations & Security
Monitoring, incidents, backup/DR, change management, AD, Entra ID, IAM/PIM/PAM and regulated environments.
Certifications & professional training
Formal validation of skills built over years of hands-on work.
Selected certifications cover networking, information security, virtualization, VoIP and IPv6. Older credentials are included as a record of the technical foundations I continue to build on.

Selected case studies
Problem, action, outcome.
A compact view of what needed to be solved, how I approached it and what changed technically or operationally.
Repeatable deployments instead of a manual process
- Problem
- Contact-center environments needed a deployment process that could be reused by implementation and support teams.
- Action
- I built an Ansible framework with reusable roles, structured inventories, environment-specific variables and standardized playbooks.
- Outcome
- A documented, repeatable deployment process with procedures that could be reused by other teams.
Approximately 900 VMs from on-premises to AWS
- Problem
- Migration of a large virtualized estate from an on-premises OVH environment to AWS.
- Action
- Terraform and Ansible were used to standardize provisioning and configuration for migrated systems.
- Outcome
- An automated and consistent infrastructure preparation approach for a project involving approximately 900 virtual machines.
Complete IT for a regulated environment
- Problem
- Build and continuously operate the complete IT environment of a licensed casino in Liechtenstein.
- Action
- Networks, routing, VPN, Windows/Linux, virtualization, backup, monitoring, Microsoft 365, IAM and PIM for external vendors.
- Outcome
