Hi.
I am a web development expert who has been in the industry for 4 years. I have worked on various javascript projects, oauth API integration for twitter, facebook and tumblr, and a lot of backend development on php and node.js. I don't forsee any problems in this job, and I can deliver this in 7-10 days easily.
The code will be easy and maintainable and of best quality. This is my guarantee.
Please let me know if you have any questions. Thanks
