With the Google Algorithm change on 21st April 2015 websites will need to be fully mobile responsive in order to not have their ranking position in the search engine results penalised. My 10+ years experience of delivering web project gives me the ability to troubleshoot web code very quickly. For the last 3+ years all of the work that I have delivered for my clients has been fully mobile and tablet compatible. Rarely do clients provide me with tablet or mobile designs, normally all I receive is a desktop design. I can take almost any existing website and retrofit it with a responsive CSS design that will make the website fully mobile friendly and bring your website inline with Google's requirements for their new algorithm change.
