System administration
Windows Server, Linux, virtualization, accounts, and endpoints are the day-to-day base of an environment you can rely on.

ICT System Engineer
Hi, I'm Ruben A System & Network Admin
I build, troubleshoot, and document Windows, Linux, and network environments, with automation where it makes operations clearer and more repeatable.

Focus
Where I want to build
My direction is clear: system and network administration. I like working close to the technology itself: troubleshooting, configuring, documenting, and improving things step by step.
Network administration
From network equipment to connectivity issues, I like finding out how traffic flows, what monitoring and logging show, and where a problem really starts.
- Connectivity and network equipment
- Monitoring, logging, and root-cause thinking
Automation where useful
PowerShell, small utilities, and dashboards for recurring admin work that can be faster, clearer, or less repetitive.
- PowerShell for repeatable admin work
- Small tools for visibility and handover
Approach
How I approach IT work
I work best in a practical way: first understand what is running, then document what changed clearly, so someone else can continue later without guesswork.
Operational discipline
Good handovers, clear notes, careful changes, and incident follow-up are what make a fix stay reliable after the first solution.
- Readable notes and careful changes
- Follow-up after incidents and handovers
Manageable infrastructure
A server, network segment, VM, or monitoring setup should be clear enough to work with quickly, even when there is pressure.
- Servers, VMs, and network segments
- Monitoring setups that still make sense later
Experience
Built in real environments
My experience combines infrastructure, security, monitoring, and hands-on user support in production and care environments.
Infrastructure and security operations
I gained hands-on experience with network and server management, monitoring, Linux infrastructure, and security within a production environment.
- Monitoring migration and SIEM optimisation
- Logging, abuse detection, rack migrations, and incident handling
TinyProxy management platform
I developed and brought a high-availability management platform for TinyProxy into production, including a web interface, automation, and logging.
- Web interface for operational visibility
- Automation and logging for repeatable management
Support in a healthcare environment
I supported users with hardware, software, printers, scanners, mobile devices, Microsoft 365 applications, and specialist workplace software in a care environment.
- Workplace moves, hardware management, and escalations
- Practical troubleshooting with users under time pressure
Supporting the move to Firda
Following the merger that created Firda, I helped staff move to the new tenant by reconfiguring laptops and resolving issues on site.
- Laptop reconfiguration and rollout support
- Clear explanations and issue resolution on location
Want to see what I build?
My GitHub is mostly where experiments, scripts, and small tool ideas land. It is not a polished product shelf, but it does show how I investigate and solve technical problems.
