Cucumber.js expert for selenium webdriver

I need a developer to build a set of Cucumber.js steps in Javascript for Selenium Webdriver.

The specific steps needed are a re-implementation of a set of open-source steps in Java that are part of the selenium-cucumber project.
The steps are defined here:
