I'm still unsure how much technology will be available in this world, I don't know if there will be "pockets of working grids", if people can only get energy from generators(which also adds the trouble of finding gas for it or using more "ecological means" if available) or if there is no energy available at all.
So basically everything would be done manually, the way many craftsmen used to do before we developed ways of making things industrially(fast and by bulk) This character would have their own survival skills, but I'm thinking that in a post-apocalyptic work not everyone tends to think of the commodities, like alchohol(both as beverages and for medical purposes), higyenic products(soap and toothpaste for example), sunscreen, ointments and etc. How much value would someone like this have for a group of survivors?Would they even be on demand if people know they might find some of these things while scavenging?
