I built something to manage files, should I share it like a plugin?

Hey guys, so I’m new to the wordpress development world and recently I built something to manage files here in my workspace.

Here at work we have cases and each case can have a lot of documents (pdf). The new files are being created on a weekly basis and we need to share it in a website for the public.

So I did this: I’m using the WP-API2 to create posts, and I can then select a post and upload documents to it (I created a page with a form to do that). I’m also using the DataTables plugin to list all the “posts” because each case has some metadata that also needs to be shown, so I store this metadata in a JSON.

Ok, given that, my question is: what should I do to share this project with others? Should I build a plugin? A template?

Also I would be happy to hear some feedback about it, I searched for something to feel this need but didn’t find anything, so I built my own solution. Is there a better way for me to address this need (manage documents like I’m doing)?

Thank you!
