No Problem
I can fix this with high skill of node js socket io.
I am confident that I can be a good employee for you because I know what you want. You can have a check on my profile, Portfolio, Work History and Feedbacks to satisfy your needs. I can assure you that I will do my best to do your job.
I have worked on several similar projects you want, and can deliver quality notes to tight deadlines.
If you award me the project I'd be very happy to discuss this further and get started for you as soon as possible.
Thanks!
