On what sites in Runet can you promote your project by writing an article about it?

Question

Marketing

I'm working on a project, which is a web service for automating certain routine actions. I don't have high hopes for it. If it shoots, then okay, if not, it will go into my portfolio for demonstration to future employers and customers. In any case, good practice.
The advertising budget is minimal, so after the launch I want to write an article about it, like this one: https://habrahabr.ru/post/320292/
You need to decide in advance where to place it. At the moment, I have noted the following sites for myself:
https://habrahabr.ru
https://vc.ru/
https://spark.ru/
Relevant sections on thematic forums.
Please advise more, for maximum coverage. Only runet.
