about
I'm Stefanos, a software engineer in Athens, Greece.
Most of what I build has a map or a sensor in it somewhere. I love building tools that solve real world problems and can prove to be beneficial in people's daily lives. Some of what I do is for games that I play, and most of my modding work or proprietary tools for games such as Empire: Total War is yet unreleased.
I've also worked as a tech on concert stages, enjoy electronics repair, love tinkering with bicycles as well as both drone and traditional photography, although I find the best shots are on the camera that's always with you.
I like short dependency lists, pages that load quickly, and data you can follow from one end of the system to the other. Given the choice I'll take the plain, direct version over a convoluted layer of tools that clog a system down.
I believe there's beauty to be found in everyday moments, and a few of those are captured in photos on the front page.
