One of the fun things I like to do with technology is to make my life simpler at home through automation.
For example, working from home with four small children can be especially challenging. To handle this, I use a color-changing light bulb outside of my office, tied to my Alexa so that I can show red, yellow, or green to the outside world. That way (in theory, at least), I can take important calls undisturbed by a tiny human.
I also used GitLab CI/CD to automate updates to my local DNS server and my RetroPi gaming system.
A passion of mine in my spare time is amatuer photography. Taking pictures of landscapes or my kids... I pride myself in having an eye for design.
