On-site work at NGA on the annually renewing research (RECON) contract, requiring active DoD TS/SCI with CI Polygraph.[Main Role] Lead Developer for sarpy project• Responsible for leadership and mentorship on a small software team, and communications with prime contracts and Government point of contact.• Lead the design, development, and maintenance of the sarpy project, which enables reading, writing, processing, analysis and data product creation for Synthetic Aperture Radar (SAR).• Project enables basic and applied SAR research efforts, and has open source, proprietary, and classified components. See the open source github repository and documentation.• Related secondary task involved architecting and developing creation and maintenance of sarpy_apps project, which is a small collection of desktop GUI tools enabling relevant interactive SAR visualization and analysis tasks. See github repository.• Project offers multiple successful transition pathways, and a number of NGA and other IC programs using sarpy as a critical dependency, and a smaller number intimately depending on sarpy_apps.[Secondary Role] SAR Image Data Scientist• Mentored, advised, and participated in a number of SAR image data labeling and target recognitiondata science projects, involving small to medium size teams.
