Miro Svrtan

I started using PHP as a student, back in 1999. At first I worked as a one man band web developer and from there I progressed, via focusing on PHP development in a team environment, to be a senior dev, tech lead & technical analyst.

I found much more happiness doing backend stuff so I focus on scalable backends and DevOps tasks this days.
