Is it possible for you to start a coding job where you are not coding a behemoth application, so that you are the main cog, and not a tiny part of the process?

Is it possible for you to start a coding job where you are not coding a behemoth application, so that you are the main cog, and not a tiny part of the process? I don't know your background but is it possible to do more embedded type or mobile app development? Best of luck, it seems that you are near your wits end.
