Rails full stack, with a focus on the front end
I've been building two mobile-first Rails web apps using contractors for several months. The apps work and I have a good senior back-end Rails developer working for me adding new features. But I now need a new senior full-stack Rails developer to help me upgrade/reinvent the UI/UX - particularly, making the apps look better, easier to use, faster loading, the flows more intuitive, and helping user onboarding. I need someone with very strong HTML5/CSS3/JS development skills along with full-stack Rails, to build out my ideas and improve performance.
The developer needs to be able to make changes directly to the Rails apps, including adding and changing automated Capybara/Test::Unit integration tests. Consumer-facing UI/UX design experience and interest is a plus, but is not required.
I'm looking for someone full-time, paid hourly/weekly, to work with me and the back-end engineer in a very agile, collaborative way, to improve the product and get it launched. I need the right person for several months.
Ideal candidate:
* Computer science or engineering undergraduate degree
* Several years experience developing web apps in Rails
* Interest in consumer-focused apps and friendly UI/UX
* Based in North or South America, for good time zone overlap with West Coast US each day for iterative/agile development
* Independent, not agency
* Fast written English for live text chat
* Interest in helping to shape a consumer product, rather than just building against specifications
* Possibility of joining as a founding employee in due course
I'm a self-funding, hands-on, full-time sole founder, with a strong business and computer science background. I'm based in Silicon Valley, and the ideal person would be based in North or South America, to give substantial time zone overlap for collaboration via live chat (HipChat).
The stack:
* Rails 4
* Bootstrap 3
* Javascript and JQuery. No front end framework currently in place
* PostgreSQL (relational) and DynamoDB (NoSQL) databases
It's mostly a server-side Rails apps that need some JS/JQuery for user input, validation, page transitions, widget integration
Target:
* Primarily HTML5 mobile web - primarily small screen sizes, iOS and Android devices
* It needs to work (but not necessarily be optimized/responsive for) desktop and tablet too
Tools:
* Git for version control
* GitHub for code hosting
* Code Climate for automated code quality review 
* CodeShip for automated testing
* Heroku for app hosting
* Amazon RDS and DynamoDB for database hosting
* Amazon CloudFront for CDN
* HipChat for chat
* Trello for project management
Target compensation: $35/hour, i.e. $1,400/week for full-time
