App design training series?

I am proficient in programming. But not "software development". I am making a simple app, but I want to go through the professional "steps" a team or individual would go through to bring it from start to finish. I want to be my own project manager while I'm building this app.

I am trying to gain experience by doing this. I am looking for any wholesome resource that anyone can recommend, may it be a YouTube channel, coursera course or other, that will go over the correct project management software, steps to take to make an mvp, testing regimens, delivery paths etc…

Any help with wholesome or piecemeal resources would be much appreciated!!
