About me

Behind SamiXoneis one person.

I’m Samir Brkic, founder of SamiXone Digital Solutions in Wuppertal. By day I secure networks and firewalls in enterprise environments as a Senior Cyber Security Engineer. I bring that knowledge to small businesses, practices, clubs and private customers – clearly explained and cleanly documented.

Story

From screwdriver to firewall.

Everything began with PCs: selling, building, upgrading, setting up, repairing. That taught me two things: how technology works on the inside – and how to listen to people who simply want it to work again.

Then came networks – and the question of how data gets safely from A to B. That question became my profession. Today I work as a Senior Cyber Security Engineer in network and firewall security, certified by Check Point as a Security Expert (CCSE) and Troubleshooting Expert (CCTE).

I also build software I use myself: Lernity, a vocabulary trainer with AI, and Vernity, club management software that runs in the club whose books I keep as a volunteer. Internally, I use SamiXone Sentinel every day – my own analyser for Check Point firewall policies. None of the three is a marketing project. They are tools.

SamiXone Digital Solutions brings this together: experience from enterprise environments, and a feel for the everyday reality of small businesses, practices, clubs and private customers. I work remotely or on site in Wuppertal, by arrangement. You always talk to me – and every change is documented well enough that someone else could follow it later.

Path

Five stops, one line.

Not a CV – five stops where I learned what matters.

  1. 01

    PCs

    Selling, building, upgrading, setting up, repairing. This is where I learned to find the fault instead of swapping parts.

  2. 02

    Networks

    How data gets from A to B – and where it snags when it doesn't.

  3. 03

    Enterprise security

    Network and firewall security in enterprise environments, today as a Senior Cyber Security Engineer. Check Point certified: CCSE and CCTE.

  4. 04

    Own software

    Lernity and Vernity are live; Sentinel runs internally in my daily work. I build what I need myself – and learn from it what maintainability means once software is in real use.

  5. 05

    SamiXone

    Today

    All of it for small businesses, practices, clubs and private customers. Remote or on site in Wuppertal – with me as your single point of contact.

Values

What you can measure me by.

Three words that could be on any website. Here is what I mean by them.

  1. Clarity

    Before I change anything, I tell you what I plan to do and why – in plain sentences. You get a recommendation you understand, and the decision stays yours.

  2. Quality

    Clean work instead of quick patches. I’d rather do things right once – and record every change so it can be traced later.

  3. Security

    Backups, firewall and secure access are part of every job I take on, the small ones included. Security is my day job – and the standard I hold every piece of work to.

04

Beyond work

What I run in my own time.

Neither is a side project: real users, real data, real responsibility.

Volunteering

Treasurer on the board of an allotment-garden club

I look after the club's finances and bookkeeping – and run its IT. The club software behind it is one I built myself.

  • Mail server
  • Data cloud
  • Website
  • Club software: Vernity

Self-hosted

Own projects on own servers

Privately, I run what I recommend to others – and learn from it what really counts in day-to-day operation: backups, updates, a clear overview.

  • Document management
  • Photo archive
  • Local AI workflows
  • Smart home

First conversation

Let’s talk about your IT.

A short conversation is enough to see whether and how I can help. No obligation, no jargon.
