Technology stack: ASP.NET Core (2.2), Windows Service (Topshelf), Twilio, mailgun, wkhtmltopdf (for pdf reports) and SqLite.
Background: It was developed for my friend's relative (dentist), but when it was complete and ready to launch for some reason my friend's relationship with his relative turned sour costing me my first client. After that I didn't try any other marketing even I canceled my Azure VM subscription and stooped the website.
Now the complete solution is on GitHub in a private repo and I'm thinking to make it open source. But before I do that I'd like to know what you guys recommend. Would there be any market for it? Or do I have a chance if I do some marketing?
Thank you so much!
