I have been developing web applications using javascript(jQuery Prefferd) from last 2 years. Have Experince in creating libraries and object based JS code which reduce compile and execution time. Also i make sure that the code i write will be clean and robust in all aspect. i can manage your code into an Object Oriented manner so that it will follow the principle of DRY (don't repeat yourself) and it will be easy to edit and tweak for future upgrades. Have also worked with tons of jquery libraries and created so many calculation engines and different calculators. Will surely give boost to your business.
