Hi, there.
I've deep knowledge in Node.js and have developed several project using it.
It seems there will be no problem for me to work out your project, and my bid is very reasonable.
I need 7 days for your project: a day to analyse your project, 3~4 days for development and 2~3 days for test.
If you're interested in my skills and experience contact me to discuss your project in detail.
I will be lovely waiting for your reply.
Best,
Lee.
