Hello there I hope you are having a good day,
I'm glad to tell you that I'm fully capable of coming the golang src for you.
I have done the same project for a school in my town, just that it wasn't on freelancer. If the only thing is coming out into an exe it will take me 3 days to complete your work with maximum guarantee of your satisfaction.
But if there's any other problem with your project please let me know as well.
I'm really looking forward to work with you and help you achieve your objective.
Your truly,
Saidi.
