I'm paired with a Technical Architect (more programmatic, less point and click) who I can bounce ideas off of. We have a community of people with the same job responsibilities that I can also bounce design questions off of as well (time permitting). I use those resources as well as reference architecture, internet communities and documentation to complete designs.
I think saying most people in the developing world don't have wifi or air conditioning is an overgeneralization.
I've lived in Ghana and currently in Zambia and people do have WiFi, 4G and airb conditioning. Granted there are large populations that don't have great homes, the need for electricity (hospitals) is great.
For example, at the teaching hospital in Lusaka, there isn't even running water.
I wish OP best of luck and will be rooting for him.
