Hi Jean11. Working from home in the Philippines, and collaborating with consultants, I have written in the last 10 years more than business intelligence analysis, including involvement with the Meta Carta business mapping project of the US Department of National Defense. In those GIS projects, maps are used as filters for information search; data is organized geographically and users visualize geographic relationships between structured and unstructured data. Excellent in English, Internet-savvy, proficient in research and analysis, and with an MBA in business development, I can provide you topic-specific, tailor-fit literature review on Geographical Intelligence Systems, for your dissertation, on a quick turnaround at less cost. You will find my detailed, attractive proposal in the Private Message Board.
