Hello sir,
From your project description, I understood that you are looking for a expert javascript developer. So, I am ready to start your project right now.
Why I am perfect for this project? I am a competitive programmer since I was in 8th standard. I am very much familiar with javascript, React, node.js and many other programming languages (like C++, C, python) . I love programming, It's my passion.
So, I will wait for your response,, I promise I will do my best for you.
