I have saved children from online abuse. I have identified and disabled billions of bot accounts. I’ve prevented millions of dollars worth of fraud and protected millions of users from account take-over and compromise. I protect hundreds of thousands of enterprise users from malicious software. I reduced the time to build, test, and deploy anti-abuse algorithms from months to hours. I’ve extracted meaning from one-on-one interviews and petabytes of data while building predictions systems with coverage across entire businesses and precision greater than 99%.I have twenty years of experiencing standing up new data systems, iterating on prototypes, and helping the users hidden in the data speak for themselves. I am interested in exploring the frontier of data science: the open-source stack, Python, Linux, and cloud/edge systems.Specialties:• C#, NoSQL with Cosmos/Scope, Hadoop/Pig, PowerBI, SQL Server, Apache Airflow• Additional work in Perl, Python R, Sawtooth, Mplus, MySql, Python, Shell, SPSS, Superset• 10+ years data mining experience
