I am a software developer and data scientist.My work has involved a mixture of research and implementation. I have been involved in projects including computer hardware design, developing and implementing field deployable solutions, designing KPIs and reports for business units, and building the full stack of online government services.Much of my work has been in the area of knowledge discovery, developing and using tools from machine learning to gain insights into large datasets.I have taught several mathematics courses at the University of Waterloo, the University of Georgia, and Carleton University, including calculus, set theory, cryptography, and elliptic curves.My graduate work involved examining arithmetic combinations of certain measure zero sets. Both theoretic improvements and machine calculations were necessary to obtain the optimal results.

Business Intelligence DeveloperShopify Sep 2015 - Feb 2017Ottawa, Canada AreaMy work at Shopify included finding appropriate credit card rates for Shopify Payments, developing key performance indicators for Shopify Shipping, building tools to find suitable customers for Shopify Capital, and using machine learning to create a credit card fraud detection system to protect all of Shopify's customers. Accomplishing these projects involved data ETL, analysis, and visualization, using a variety of tools and techniques including SQL, PySpark, MLLib, scikit-learn, Tableau and Mode. -
Mathematician And Software DeveloperGovernment Of Canada Jul 2001 - Aug 2015Ottawa, Canada AreaMy work has involved several areas of cryptography and cryptanalysis, as well as network security and cyber defence. Many projects have also required developing and applying machine learning techniques to the large data sets at hand. Although theory played an important role, implementing my results on our high performance computing platforms was key. This often required detailed expertise in parallel programming, where balancing network activity, memory usage and CPU load was crucial. -
Adjunct ProfessorCarleton University Sep 2001 - Aug 2007Ottawa, Canada AreaI taught several courses at Carleton, including cryptography, and elliptic curves. -
Part-Time Instructor And Postdoctoral AssociateUniversity Of Georgia Jul 1999 - Jun 2001Athens, Georgia AreaI held a postdoctoral fellowship at the University of Georgia. Most of my time was spent on research into analytic number theory, though I also taught several calculus classes.
