Software Engineering Experience at SDSL

In 2007, I joined a renowned software development house Structured Data Systems Limited (SDSL), an offshore development company of Afrigis, South Africa as a software engineer. There I contributed in the development of social networking platform ‘GRID’ and then led a team of sixteen developers for the development of small scale search engine ‘iSearch’. My experience at SDSL is given below:
