Thomas N. Agency Contractor

MD student w/ skills: Python, Excel, Data Science/...

United States - Last active: 1 month ago - Tests: 7

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.

Data Scientist

Argentina - Last active: 2 months ago - Tests: 4 - Portfolio: 6

What are the most relevant variables? How are they related (if any)? What values must they take in order to explain some event? I'm familiar answering this kind of questions, as well as making graphs to show information, making automatic systems to process and make predictions, and all kind of data science stuff (founded the site datascienceheroes.com) Further than working as a consultant, I can teach you how to build solutions through R. From Data Science theory to the building and application of your own predictive models, based on your data. I've been doing data analysis for the last 9 years, working in several industries such as telco, banking, farming, financial, social network analysis, bio-technology, oil and NGOs. My education is based on Information Systems (holding a PhD degree) Contact me if you have questions to address through data, or if you want to learn R in a very didactic way.
