Mostly JS and its bucket of related architectures and connections, since that seems to have the widest applicability. Also considering C++ and Java since I already have some experience in those. My parents are bordering on elderly and need more and more help, so I'm probably limited to the Rocky Mountain or southwest regions of the US. Although in this early stage when I'm just trying to get a feel for the market, I've not been limiting my searches to any specific region (other than US-based).
