NOAA/NESDIS/CLASSNOAA’s Comprehensive Large Array-data Stewardship System (CLASS) is an enterprise IT system in support of NOAA environmental information archives.As part of a team, developed and documented a Long-term Architecture Plan—compatible with OAIS-RM. Level 1 requirements, Interfaces, Business rules, and Controlled vocabulary. Directly advised NOAA Program Manager. MS Word, Visio, UML, OAIS-RMDeveloped and maintained search algorithms—including geospatial search specialized to low-Earth-orbit (LEO), polar orbiting, and geostationary satellite data—for both relational and document oriented databases. Java, C++Developed and implemented an innovative approach for spatial search of polar orbital data. Improved speed and efficiency by 10x. Java, C++, MathematicaDeveloped a new algorithm to improve accuracy of spatial search of geostationary data. False negatives reduced from up-to 90% to near 0. False positives reduced from a worst-case 100% to theoretical best possible performance). Java, MongoDBAs part of a team transitioned inventory holdings and Access functions from relational to document oriented (NoSQL) databases. Java, Spring Boot, MongoDB.

Supervised group of 10 programmers working with a broad spectrum of data types to facilitate data processing, utilization, access, and scientific research.

Development projects included sensor and physical process modeling, process optimization, pattern recognition, statistical analysis, geolocation, interpolation quality control, searching, cataloging, visualization, and animation. Other activities included design and specification of hardware systems.• Preparation of reports, journal articles, and oral presentations.• Participation in international meetings, cross-organizational working groups, and standards development processes.Data sets ranged from in-situ hand-written logs to satellite remote sensing; microwaves to gamma rays; backyard measurements to certified weather reports. Data ranged from pole to pole; covering land, oceans, and atmosphere; global climate to individual ice crystals; ocean depths to mountaintops.

Led multi-disciplinary, cross-organizational development team on project to design and build a digital map database and GIS workstation with embedded expert system and inference engine for automated mobile target search. Analyzed requirements, developed operations concept, selected hardware, developed system architecture, and supervised system development. System was successfully deployed and utilized by U.S. intelligence agency.

Implemented real-time "speaker identification" and "keyword spotting" algorithms in digital signal processors. The system was successfully deployed in support of U.S. gathering of international telecommunications intelligence.

Responsible for design, implementation and optimization of all embedded real-time mathematical functions for the prototype Digital Stereo Comparator Compiler (DSCC). The prototype DSCC was successful and our division was awarded a $100 million follow-on contract to build production versions for the National Geospatial-Intelligence Agency.
