Integrating Java based backend with UI

Hi, We are looking for a rockstar Java developer, who can quickly integrate our Java based backend with client side (UI) This is a web application (web portal). As already indicated, all server side code is written in Java & we use RESTful APIs. Frontend is on HTML/CSS/jQuery (on bootstrap framework) The html pages are available & ready. And there is a lot of server side code already written. To speed up the deployment, we are looking for an intermediate/expert Java developer who can integrate the server side code with the frontend. Exposure to Amazon Web Services hosting environment & bootstrap framework for UI will be a plus, but not essential. We would prefer Bangalore based candidates, who could spend atleast one day per week working from our office & rest of the time working remotely. Since exact nature/amount of work can be ascertained at this time, please bid for 60 hours of work (ie sort of part-time,15 hrs a week) per month. For the suitable candidate who proves his worth, this has the possibility to be be a recurring longer term contract & we can revise the pay package to reflect performance.
