I think it is cool you want to do this and there's no shame in a job while you do things on the side. I'm not sure about the idea of moving to a place entirely to be around other tech people. If you have an interest in places like Germany you should go there. You will be able to find tech people nearly everywhere. Your interests outside of tech will be what makes you interesting and binds you with other people. You find more quality dates outside of dating apps and singles nights right? It's the same thing. Also I would say in a tech hub or not probably isn't THAT important unless you are raising money or going through a tech accelerator. A small group of say 5 dedicated tech people (like I found in Taiwan) was much closer to break into than my group in San Francisco. Publicly responding is better than DMs at the start, I'm not sure why. People get weird about it. Twitter, Hackernews, Meetups, NomadList, Tech discords and slack groups are all fair game.
