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

A lot of my work starts with a VPS or a dedicated server, on Hetzner, AWS, Google Cloud or bare metal. I’ll install it, look after it and add Docker where it makes sense. Moving your sites to a new host can be done without downtime, and if a server has become slow, I’ll find out why and fix it.

WordPress & WooCommerce

Need a WordPress website or a WooCommerce shop? I’ll build it, connect the payment gateways and take care of updates and backups once it’s live. If your site has been hacked, I’ll clean it up and close the hole the attackers got in through.

Forums

XenForo, vBulletin, IP.Board and phpBB are all familiar ground. I can get your forum up and running and keep it that way, with upgrades, add-ons, spam protection and everyday maintenance. Running a few forums of my own has taught me what a community needs to stay active.

Domains & e-mail

Domains are the easy part: registering, transferring and managing DNS. Getting your e-mail into the inbox instead of the spam folder takes a bit more care, and I’ll make sure it gets there. 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

When a computer acts up, whether it runs Windows, macOS or Linux, I can connect over TeamViewer or remote desktop and sort it out there and then. Building VPNs, configuring Veeam backups, removing viruses and recovering lost data are part of the job too.

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