Professional Experience
Systems Analyst Remote Sensing MDA Information Systems LLC 07/2015 - 07/2016
Software maintenance and engineering analyst focused on company's large-scale remote sensing and
image processing software suite. with other responsibilities and assignments as required by budget
and workload. Contributed enhancements and fixes to legacy software suite and developed new
software to meet new customer requirements
• Built components of a RESTful software suite integrating multiple hardware and software
components of a remote sensing ground terminal system. These components played a critical role
in the system achieving the next steps towards becoming a DoD program of record.
• Modernized the version control and configuration management system for remote sensing and
image processing software suite by migrating from Accurev to git
• Enabled the migration of legacy remote sensing and image processing data into a new architecture
by developing software to convert the legacy data to match new specifications.
Applied Research Mathematician National Security Agency 10/2010 - 07/2015
Technical employee analyzing a variety of technical problems relating to signals intelligence and
writing code to solve them.
• Invented and prototyped, and integrated an algorithm to extract superimposed text from color
images extracted from video into an end-to-end video processing product that achieved very low
rates, significantly reducing analyst workload
• Built emulators for and implemented cryptanalytic attacks against an assortment of cryptologic
products

2. Dr. Timothy Vis 10237 Dogwood Street, Firestone, CO 80504 Timothy.L.Vis@gmail.com
• Designed and implemented cryptanalytic tests that aided in the diagnosis of cryptographic
systems
• Developed a program to categorize unknown certificate and key files used in trust infrastructure
• Analyzed security of lattice basis reduction algorithms and improved lattice basis reduction
software, giving it the ability to explore and evaluate a much broader variety of algorithms
• Led efforts to detect and counter malicious internet activity with sufficient certainty and
timeliness to prevent or minimize adverse effects, including crafting specific requirements for
several systems designed to detect numerous types of potentially malicious activity
• Wrote and presented several universally well-received technical briefings and papers for both
expert and non-expert audiences
