Technical Articles about Heroku

I'm trying to find a freelancer(s) to write a series of guides on various aspects of getting started on Heroku.

Examples:
- How to Deploy Rails to Heroku
- How to Deploy Laravel to Heroku
- How to Deploy PHP to Heroku
- How to Deploy Express/NodeJS to Heroku
- How to Deploy Python to Heroku
- How to Deploy Django to Heroku
- How to Deploy Flask to Heroku

An example of the type of guide I'm looking for would be something like this:

https://medium.com/better-programming/deploy-your-app-for-free-in-7-easy-steps-thanks-to-heroku-dfd0f387edd0

But with more details on setting a custom domain and some other security restrictions.

I'm deliberately posting this under "Software Development" and not content writing as I'm more concerned about getting the technical aspects of this correct than the copy (which we'll modify).

Thanks,

Mike
