    Over the last 7 years, I have developed a wide range of websites using HMTL, Ajax , PHP, and MySQL including sites for startup companies and small businesses. I have developed a CRM named Online Management System (OMS) for an insurance company. The main functions of the CRM are capture leads from multi campaigns, make PDF quotation according to different insurance options, track leads' sale progress, a basic report function. I also have developed a platform,both frontend and backend, which is named TAP (The Advocacy Platform). TAP is a gamified marketing platform which delivers research, user generated content, and most importantly transforms consumers into true authentic Brand Advocates. Advocacy campaigns via TAP have delivered key message recall of 40-50% at 1/10th of TV media cost. Fueled by a community of over 125,000 women in the top 20 cities in China, TAP has delivered 5 million brand 'missions' since January 2012 for key clients such as Reckitt Benckiser, P&G, Kimberley Clarke, J&J, GSK, and Fonterra. My core competency lies in complete end-end management of a new website development project, and I am seeking opportunities to build websites from the ground up for you or your business.  less
