About

Welcome to my playground!
I'm a professional, highly experienced software developer and architect. My background ranges from mapping business processes to low-level software and data optimizations.
When not busy with work or life, I love bringing my camera and create photos and videos that can portray the experience!
The name "ethlo" used to be my company name, and has been with me since I started doing professional software development, and has stayed with me. Since I find it short and sweet, I use it as a signature on things I have created.

Fun-fact: The name stems from the Linux ifconfig output, listing network interfaces, usually listing eth and lo as standard devices.
