I am a C# developer that tries to work after clean code principles. I value good code that is properly tested. Everytime I have to do something cumbersome, I wonder how to automate it, which is how I ended up with some interest in, amongst others, build automation and automated UI Testing.
If I code in my free time, it is usually playing around with some technologies I don't work with, for example machine learning with Python. I play around with my Raspberry Pi, creating things like a build lamp that shows the status of the last CI build or automate my appartment with some speech-recognition software that can turn on/off lights, my TV etc.
