Hello,
I've read your description carefully i.e "Need mongoDB developer to stop unexpected" and are very interested in your project and can implement your project. It would be great if we can have a detailed discussion regarding the project requirements so as to make sure that we both are on the same page and can get started with this.
Thanks,
Jaimin P
