    Richard Rymer

    researcher and data analyst

    United States - Last active: 12/26/2014 - Tests: 1

    I am a data analyst and scientist with over 10 y of experience. I have used predictive analytics to improve the yield of an industrial process, and historical data reviews to identify common false failure modes for quality control metrics. More recently, I have developed data acquisition automation methods (using python and MySQL) for an academic research project. I excel with noisy, messy data sets, or where it is unclear how to get the data needed to solve a problem. What I am good at is finding data, and turning those data into information. I am seeking opportunities where data and data analysis are needed to move a project forward, impact the bottom-line, or solve a problem. Technical Skills Analysis Software: JMP, R, Excel Coding: Python/MySQL/bash primarily, but also JSL/R Visualizaiton and reporting: Word, Powerpoint/Keynote, Adobe Illustrator,Photoshop,InDesign,Premiere

    I do data. Spreadsheets need to be cleaned and standardized? Done. Using multiple vendors for a project and the data doesn't sync? I can fix it. You read about how "data and analytics" is all the rage, but don't actually know what that means? I can translate for you. I have been working in political data for seven years. I have worked for big names and know their tricks. Tell me what you need and I can get it done.
