About me
I'm Mate Burazer. I've been around systems and networks in Croatia since my first apprenticeship in 2015, and for the last few years I work on customer premises equipment at A1 Hrvatska: testing it, breaking it in the lab and sending the results back to the vendors.
As a kid I wanted root on everything I owned, including a couple of odd mobile operating systems such as MeeGo. That habit turned into a job, and I never got bored of it. Two degree papers later, one about Wi-Fi security and one about network traffic security, I have a master's from TVZ. Away from the keyboard: games, books, films, music and amateur radio.

Hardware and software refresh with automated records
IBM Maximo SCCD · UI.Vision RPA · HBOR, Feb – Jun 2021
Replaced ageing hardware across HBOR and handed new equipment to every employee, each one with written instructions. Every machine went into IBM Maximo SCCD, and the repetitive clicking around that database was automated with UI.Vision RPA macros.

Aurelius Multitool, a Windows utility suite
One launcher that bundles service monitoring, troubleshooting tools, media utilities and a couple of games, so the things I open every week live in one place instead of five folders.

Amateur radio
My station log lives on QRZ.com. Press the little speaker next to the callsign chip up top and you'll hear it sent in CW.
QRZ.com profileLocal AI models
Quantised GGUF models running on my own box, inference tuning, small agents. Mostly to see where they get things wrong.
Home lab
Off the clock I still play with routers and CPE: Wi-Fi surveys, firmware updates, TR-069 experiments on my own network.
