Where do you share ideas and get feedback?

Hi, I have a problem maybe someone can help me with it. I'm a software developer, and I maintain a solid tech stack (UI/UX isn't great but I'm working on it). I am capable of designing, developing, and deploying an application from start to finish. The difficulty I am having is how to reach users, my distribution stack is poor, very  poor. When I google this problem and watch youtube videos, the solutions do not seem real.  It is essentially getting a bunch of fake people to attract not fake people and spam.  Product Hunt is the only place I've found that looks and feels honest where I've found tech that I'm using on a daily basis.  Do you know of more places like this where I can promote with more idea minded people to get feedback? Thanks for your help.
