Dear Carlton,

It would be best if you can submit them to one of the Odoo Community Association repositories:

https://github.com/OCA

Please review the existing projects and if there's one that is aligned with the changes that you have introduced, fork it, add your new modules and send a Pull Request for revision for merge.

You can find more information about the Odoo Community Association here:

https://odoo-community.org/
