    Thomas N. Agency Contractor

    MD student w/ skills: Python, Excel, Data Science/Analysis/Viz/Scrape

    United States - Last active: 2 months ago - Tests: 7 - Portfolio: 6

    Over the past 5 years, I have developed a unique skillset that is mainly focused on manipulating, visualizing, and understanding data. As a medical student, I've utilized big datasets distributed by the CDC and other governmental organizations to find and anlayze trends in healthcare for research. My core competency lies in utilizing everything from smaller datasets in Excel to writing complete programming solutions to handle very large and complex datasets. I work primarily in python using the main data science libraries (pandas, numpy, scipy) as well as scrape my own data directly into a database using other python libraries (beautifulsoup, mechanize, scrapy). No matter the project, if my studies allow me to have available time, I can complete your data analysis, database manipulation, and other data related projects for you or your business efficiently and with close attention to detail. I also have experience in the following areas: SQL, MongoDB, Microsoft Access, and javascript libraries such as charts.js or D3.js. I am also very familiar and comfortable with medical terminology and am capable of distilling the information in to more accessible terms. I know how difficult it is to understand sometimes but I am able to generate content or review/edit content utilizing my medical school education.
