Data Scientist (Tumblr, eBay, Brown University)

Data scientist with over 5 years of experience at major tech companies (Tumblr, eBay). Brown University graduate, expert level at Python and SQL. Jack-of-all trades skillful at every step of the data pipeline: I can set up your AWS - SQL connection or write your ETL in SQL/Python; I can extract data from whatever source you need me to; I can clean it, munge it, and pipe it into whatever form you need, including Excel or Google sheets. I'm also good at shell scripting, Python for non-data purposes, general data analysis, and simpler data flow setup. Wondering if I can help? Just ask me! I'm a woman so if I'm not actually qualified for the job, I'll be honest with you :)
