Oh, my above post is referring to living in Bangkok City in Thailand. Here are some visa information:

I believe you will need a business visa to legally work here (I am a Thai national so I do not have that issue) and getting one isn't a trivial task, unfortunately.

I suspect that the OP is most likely working using a tourist visa. IANAL but it is likely not legal if caught, but if you can get away with it, more power to you.
