使用自定义HTML表单创建joomla文章

I have a custom HTML form that i would like to use to create Joomla! 3.5 Articles with it. but every other extensions offers me "extra fields" and no way of customizing it or any of it's functionalities.

please do not suggest me extensions, I would like something more reliable even if it involves creating a new module/extension.

Thanks.
