Hi, we are building a web application in Ext JS (Sencha) and need short term on-site support for CSS/HTML to implement styling features and cosmetic improvements in line with PSD designs that are being done. Work is full time or part-time and paid on an hourly basis but at least 70% must be on-site at our office in Noida, Delhi. Contract duration is 4-8 weeks, with option for extension, more remote working or even hire to full time position for anyone hired who does a great job.
