I suppose it can, but the code would have to be written prior to that and/or outside the US. The bottom line is that you can't work for money in the US, whether for yourself or somebody else, if you don't have a proper work visa. And you can't get a proper work visa, unless a company sponsors it for you. And you can't sponsor your own work visa.
