Data | Programming | Systems

I work as a systems architect and statistical programmer.

Systems architecture has meant collaborating with end users to design analytics platforms that scale to their need, then using application programming, secure networking, and sysadmin tools to develop and deploy that platform. My statistical programming experience includes data ingestion and ETL, exploratory data analysis, modeling, and reporting.

Selected Work History

Data Systems Architect

Summit Consulting, LLC - Washington, DC

June 2014 – Present

At Summit Consulting, I support the Litigation Directorate's quantitative expert witness services. I also act as a technical expert across Summit’s portfolio, providing consultation on cloud computing, distributed systems, big data, machine learning, databases, and version control.

Project examples:

  • Improved the runtime of a computationally intensive model from 180 hours to 19 hours with parallelization on cloud resources, introducing cloud computing to the firm. The reduction made it feasible to update, and render more defensible, an econometric model submitted as expert witness material in $20+ billion litigation.
  • Transitioned internal staff and external teaming partners’ work onto a shared cloud platform to solve coordination and data sharing problems. The common working environment was provided seamlessly and securely using network controls, user access management, a network file system, imaging, and a hosted code repository.
  • Automated report generation, saving more than 25 skilled labor hours at each iteration of data and incorporating continuous quality control, using Python to interact with AWS, R, and Stata.
  • Researched, implemented, and reported on robust regression methods ultimately included as the method of choice in expert witness testimony.
  • Rewrote a data ingestion pipeline using shell utilities, improving processing time by orders of magnitude and avoiding conversion artifacts from unintended type enforcement.
