Systems are approached as things that must be operated, diagnosed and maintained — not just installed.
I work across the boundary between IT infrastructure and industrial systems: Linux servers, web platforms, networking, security auditing, PLC/HMI environments and the protocols that connect them.
My approach is deliberately practical: understand the existing system first, make changes that can be explained and reversed, and leave the environment easier to operate than it was before.
Modern infrastructure rarely fits into one box. A performance issue can cross web servers, databases and networking; an industrial integration can involve PLC logic, Ethernet, operating systems and security policy.
Working across those layers makes it possible to diagnose the complete system instead of stopping at the boundary between two vendors or technical teams.
Linux servers, web platforms, databases, mail, DNS, storage and production troubleshooting.
PLC, HMI, field devices and industrial networking for both new and existing systems.
Security auditing, hardening, firewalls, VPNs, routing and network troubleshooting.
INN deployments, peering, filtering, migration and long-term historical archive work.

Describe the system, the constraints and the result you need. I can help determine where the problem actually is and what should be changed first.
