Happy to pay. Really would benefit from you and your better debug skills looking over my virtual shoulder.
By your API you mean some custom rest API or API of a library you are developing?
I would be happy to help, however the only issue is to synchronize our time as my local time is EEST.
If it’s something big you can just create a job offer or pm me directly as my company provides Elixir/Phoenix consultancy services. 
Recently I helped rewriting avatarex library. My changes have improved a compilation time, library API and documentation.
