What do I do? (I will not promote)

I am new to building and I am quick about creating solutions and products but marketing and getting users is the main issue I face. I think of ideas, and since everyone is using AI to build, I do the same to build beta product asap but after that I get stuck. Here are the platforms I try to post on: LinkedIn : Over 2k followers but I think it has less relevant crowd. Reddit : people ignore or report because of marketing HN : i have been an active user but they flag the post mostly and remove it Product Hunt : I avoid unless I have some real users Discord/Slack/Dev.to like platforms : but because of vibe coders, markets are getting saturated. I think a couple of my ideas are actually good and I am still working on them but because of the saturation, nothing much fruitful. I am genuinely frustrated because of this and I work as a backend developer for a broker that makes my life more difficult as it leaves me very less time for it. I can't even leave my job because of liabilities I have. If you people could really help me, that will be great.
