Build me a custom Gatsby plugin

Job ID: 32199760

Budget: €8 – €30 EUR

I'm looking for someone to create a Gatsby plugin based on the Gatsby boilerplate. It's for a web analytics tool using an API. The plain script looks like the usual <script code=28472 id=39742 domain.com <script>.
I need the developer build it in such a way the variables can be defined in a Gatsby config file. I've got examples.

This task is pretty straight-forward and due to the available resources a realistic 1-2 hour project. I'll hire the person who can start working on it now. In case we have a match, I've got the same request for other frameworks as well.

Not looking for agencies or long-term projects. Please refrain from applying in that case. Thank you.
