A blog post is a great opportunity to demonstrate the project without people needing to do anything (except read). That said, people using search will probably only see geeks for geeks, stack overflow, reddit, and a bunch of SEO garbage. Probably it helps to drop the link (noncringily) in discussions about that problem.

If you don't mind me asking — could you share which blogging platforms you recommend?

I live in Asia and only know local platforms, but since the user base is quite limited here, I'm looking for platforms where I can post in English and reach a broader audience.

They mean set up your own personal website and blog and get into the SEO game. Hint, it's actually not too difficult if you're writing a lot and also are able to write about something people want.
