Hi there, I'll try and keep this short to save you time, but here goes. Hi, my name is Toby, I'm a 17 year old A-Level student looking to create a freelance portfolio before I leave school. I have over 7 years experience working with computers, with at least 5 years working with c# and similar technologies (through making games with unity and making software with Windows forms).
In the tags of your project you put a lot about c# and the .net framework. While I'd be more than happy to work with this for your project, could I recommend using electron js and Web technologies as a different solution? This would allow you to port the software to a Web app much easier. Just a thought.
As for my experience, I have previously made software for a client using electron js, however I am more than comfortable using c# for the application you are after, having lots of experience in things like web requests from having created multiple online games.
You can find out more about my freelancing history here: https://tobycsmith.com. (just as a warning this page is still in development so may be missing information, sorry!)
I hope to hear back from you soon, also the price is definitely negotiable, and the delivery time may change when I get more information about the project. Thanks for your time!
