Dear Client.
I have read your description very well. As a full-stack developer, I'm specialize in Database.
"MySQL, MSSQl, Oracle... is my major". So I think that I can complete your project perfectly.
I can provide better work than you expected, I have already done a lot of work, and my clients are 100% satisfied, so I hope you enjoy working with me.
But now I can't sure about the timeline and budget because I don't know the detail of your project.
So I want to discuss your project in detail via chatting.
Regards.
