About me

System administrator

Hi, I’m Amar, known online as Amadex. I work as a senior system administrator at a web hosting and digital marketing company. Most of my day is spent on Linux servers: keeping them updated, fast and secure, and figuring out what went wrong when something doesn’t behave.

I built my first websites back in 2008 and never really stopped. Amadex started out as my own small IT company, looking after hosting, websites and servers for clients. It’s no longer a company, but I still take on freelance work under the same name.

In my free time I run a few community sites of my own, which you’ll find under Projects, and I spend more time than I’d like to admit playing with AI tools.

I live in Zagreb and speak Croatian, Bosnian, English and German.

Since 2008

What I can help with

Alongside my day job, I work with businesses and individuals on servers, websites and everyday IT. Most requests fall into one of these areas:

Servers & hosting

I install and manage VPS and dedicated servers on Hetzner, AWS, Google Cloud or bare metal, with Docker where it makes sense. I’ll move your sites to a new host without downtime, and if a server has become slow, I’ll find out why and fix it.

WordPress & WooCommerce

I build WordPress websites and WooCommerce shops, connect payment gateways and take care of updates and backups once the site is live. If your site has been hacked, I’ll clean it up and close the hole the attackers got in through.

Forums

I can get a XenForo, vBulletin, IP.Board or phpBB forum up and running for you and keep it that way, with upgrades, add-ons, spam protection and everyday maintenance. I run a few forums of my own, so I know what it takes to keep a community going.

Domains & e-mail

I register and transfer domains, sort out DNS and make sure your e-mail lands in the inbox instead of the spam folder. I can also set up Microsoft 365 or Google Workspace for your team, along with a newsletter system if you need one.

Remote support & backups

I can connect to your computer over TeamViewer or remote desktop and fix the problem there and then, whether it runs Windows, macOS or Linux. I also build VPNs, configure Veeam backups, remove viruses and recover data when something goes wrong.

If what you need isn’t listed here, send me a message anyway and I’ll tell you honestly whether I can help.

Hobbies

Off the clock

After work I’m usually still in front of a terminal, tinkering with something self-hosted. If it can run on my own hardware, it probably does.

The other hobby is watches. Most days I wear a G-Shock GW-5000U-1, and the Tissot PRX comes out when I dress up a bit.
