I am a software developer. I would like to be a freelancer and have a s much freedom as possible.
Work completely remotely.

I got interested in e-Invoicing , PEPPOL, UBL21, Cross Industry Invoices, SMP, SML, Peppol directory and related topics.
I did some projects in C#.NET and C#.NET Core related to PEPPOL and e-Invoicing.

I would like to focus on C#.NET Core because it is multiplatform and could be an alternative to JAVA.

I noticed most of the working and reliable building blocks are written in Java but they have enormous dependencies and are difficult to alter.
For companies that want to use PEPPOL in C#.NET it is difficult because they need to program a lot themselves
because the opensource repositories in C# are limited as opposed to JAVA repositories.
Most of these companies are writing similar code but they do not want to share it because they invested a lot in development.

If all companies who are using C# for PEPPOL and e-Invoicing or are planning to do it in the future,
would all give a small monthy amount for sponsoring, I could continue to write libraries and later working applications.
Those companies will need less investment in coding.
If there is a company willing to give an important amount monthy, I could put there company name in the namespaces as most important sponsor, with would be good publicity.
For smaller amounts but still significant I could mention the company name in comment as an important sponsor.

If there is no interest my hobby and passion will probably fade after a while and many people will do similar things besides each other.
