Help regarding publishing stories online

I write stories as well as scripts for movies. But I have no idea about a good platform where I can publish them so that they can get attention from readers as well as reviews.

I want to establish myself as a writer in the community, money isn't my priority, I want to express my imagination to the public.

So, I want recommendations on some good platforms which will give me exposure. I'll be thankful if I get some help.
