I am looking for a ruby on rails developer to fix a few things on a current app and start development on a new one as soon as the current issues are fixed. Please be current with the latest releases on Ruby and Rails (i.e. 1.9 and 3.1+ respectively). You should be comfortable with UI as well as back end. Also you need to show demonstrated experience in working with payment gateways in particular authorize.net. Also, it would be good if your resume showed some experience in having ROR work with native and web mobile apps for example, use of JSON created APIs, shared authentication etc. Please do not apply if you do not have a resume with depth of experience in the areas I outlined above.
