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

    United States - Last active: 8 days 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.

    Ukraine - Last active: 1 day ago - Tests: 4

    I have 10 years of experience in different areas of software development. My most recent experience lies in field of backend development of horizontally scalable solutions for data processing. During last 2 years I have been developing from scratch proprietary framework similar to Apache Hadoop and Spotify Luigi for batch data processing (billions of log records of ad data daily). I used Python as core language to promptly prototype data analytics business logic with a goal to rewrite it in native language without API changes later. This project also involved managing NoSQL databases (TokuMX or MongoDB 3+ with an appropriate storage engine) to process, aggregate and store massive (hundreds of millions daily) number of documents, indexed for further statistical analysis and reports generation. I also have experience in the following areas: - development of web backends in Python using uWSGI and Tornado frameworks - automation of code building and deployment, Vagrant, Docker - C# language and some experience in Java and C/C++ I am an open-minded technology enthusiast with strong algorithmic and mathematical background and keen attention to details. New language, technology or framework required for next project is not a problem to learn at all. I am ready to show positive, constructive and helpful attitude to your tasks.
