I hope I will manage to explain what I want to say and that this is the right place to post this question.
As in many other professions there are some small jobs that you can do as a hobby to practice one profession.
I.e. If you want to practice carpenter you can do some bricolage at home or do it paid for the others. If you want to become a chef you can make some cake at home and try to sell it.
Do the same exists for game industry? I have some programming and management skills and I could try to use them to make some small tasks for some game firm or for some indie team and to earn some pocket money from these things. Since I'm a web developer I know that there could be some chances of such small jobs in testing. Maybe there could be such small jobs also as a help desk service to receive bug records?
Thank you for your responses!
