How would you improve a third world country?

I'm an immigrant from Nigeria in the US, and I've only ever wanted to live in a place with a good quality of life, which I believe all humans deserve regardless of their country of birth. I'm not loyal to Nigeria, or the US or literally any state on earth. I just want to be in a place where I'm free from violence, starvation, loneliness and physical discomfort. This is hard, if not impossible to get in Nigeria, as a middle-class person. But the way the world is looking, and the US, it seems I'll have to return home earlier than expected. I was always going to return to Nigeria, because I don't want to be a second-class non-citizen in America or anywhere else on earth for that matter, and being in your home country is the best bet in today's world especially if you're not white (argue with your mom, not me). But ideally I would have gotten more established financially and experientially so I could build a better life for myself and others in Nigeria. Which brings me to here. 23 year old female- $10k to my name tops. Bachelors degree in Chemistry but I'm not a genius or anything- I'll synthesize stuff if you give me the tools and instructions but I'm not getting a Nobel prize or a PhD anytime soon. Assume I'm going to the middle of bumfuck nowhere in Nigeria- no protection from the environment (it's extremely hot), no good reliable and affordable ways to build infrastructure, no affordable transportation, no job (cos nothing works remember), no security, food prices through the roof. Literally just lawlessness and poverty. What on earth am I supposed to do besides die? I'm not even being cheeky here- I genuinely want to create a good safe community for myself, my family and all other humans around me but I'm one young woman with no practical skills and no money and no backing from a benevolent wealthy organization. I want to harness solar power for example, but it's so expensive, and hardly anyone in Nigeria is trained to build and maintain it. I don't know what would be the most lucrative crops to grow if I wanted to start a farm world do. I don't know what I'd do if I bunch of men with guns showed up to take whatever little I build. Any skilled Americans or people generally, want to come with me a kick start a self-sustaining community that works? I don't know anything about management or politics? Basically like all you privileged fucks, I can only survive in a civilization, and I have to return to a barbaric place. Nigerians themselves will tell you the situation is hopeless, but I'm not going to pathetically beg the US for residency if they've decided to become ethnonationalists, so I have to go fight a corrupt system.
