I require a developer who's familiar with the dealing of client-side through express (a function provided in the node.js app will be used by the html/ejs page and called by ajax). If you're familiar with this, please let me know through PM. It's a little task of 15-30 minutes, so a little payment of $20.

Great! Replied to your PM with all the details; please do lemme know if you think this amount is enough for it and if you can do that.
