The list (of projects) was carefully picked based on amount of fees I received, knowledge I acquired, efforts taken and most importantly stuffs I could remember. There are some more — according to programming — things (which I might later put them on the list) I've done. Such as WiFi reconnector, Arduino-involved stuffs, WhatsApp broadcaster & auto reply, chat bot (including WhatsApp), etc.

I'll try to list them all while fixing my English at my leisure.
