well, I was about to make such a topic myself. However, I am less talented than you.
I am good with PIC and Arduino, I didn't try ARM MCUs but I think I have no problem with them too. my other skills are fairly good as I designed a graduation project (Solidstate ATS) which combines nearly everything in electronics and embedded systems.
If anyone know where I can get a job (work from home or something), please PM me.
thanks
