Multi-siteinfrastructure scope
01 / EXPERTISEInfrastructure as a system,
Infrastructure as a system,
not a set of technologies.
My focus is the interaction between compute, storage, networks, monitoring, security and operations — and what happens when individual components fail.
Virtualization & Storage
Highly available virtualization platforms, distributed storage and backup infrastructure.
Networking
Multi-site networks, segmentation, routing, VPN connectivity and resilient Internet access.
Observability
Metrics, logs and alerting built around infrastructure visibility rather than isolated monitoring checks.
Security
Security monitoring, system hardening, access control and practical infrastructure risk reduction.
Infrastructure Operations
Architecture, migrations, incident response, documentation and technical team coordination.
02 / SELECTED WORKEngineering decisions
Engineering decisions
with operational consequences.
Selected infrastructure areas based on real production work. Detailed case studies will be added without exposing client networks or confidential data.
Multi-site Infrastructure
Architecture and operation of infrastructure spanning multiple locations: segmentation, secure inter-site connectivity, routing and centralized services.

From troubleshooting individual systems to designing the infrastructure around them.
I work at the intersection of hands-on engineering and infrastructure ownership: architecture, implementation, production support, incident response, migrations, documentation and team coordination.
My strongest area is heterogeneous infrastructure where Linux, virtualization, networking, storage and security have to work together as one operational system.
