I'm in a similar boat and I"m not doing it full-time. So my time is precious.

I keep it simple in terms of planning and organisation. I use a set of Markdown text files for now since I'm alone and I develop as if I was on a team. I don't cut corners in setting up projects, repos, and code quality.

I'm afraid of bogging myself down and slow my development speed but at the same time there's going to be a point where another person will join me.

You're probably doing just fine. Just be on the look out for not putting more planning before its time.
