Software Consultant: Providing development services under USAF SBIR subcontract. Performed overall system design, algorithm development, and subsystem vendor selections. Used innovative methods to optimize the development cycle and the overall system performance. Wrote embedded Java, C firmware, for electromechanical satellite tracking system. Ported an open source C-based satellite-tracking algorithm to Java. This saved the project tens of thousands of dollars. Conceived and wrote several pending patents and brought the IP to the business development phase.

Lead Software Engineer: Team leader and founder of five-member Software/Firmware Group for DTC RF products. Decision-maker for all aspects of development, including development tools, source control, microprocessor selection, and system protocols. Brought company from zero software engineers and zero source lines of code (SLOC) to five engineers and over 65K SLOC. Cross-functional execution in desktop GUI’s, embedded/real-time firmware, hardware engineering, marketing and manufacturing resulted in products that performed in multiple dimensions.

• Designed and coded DTC's Universal Configuration application. Introduced and promoted the advantages of Java and JBuilder. Specified and implemented a universal system protocol, Java dynamic class loading, serialization, and introspection to maximized reuse. The application supported over 30 device types, was very easy to use for non-technical customers, and was an industry-leading capability.
• Used market awareness, championed use case driven requirements, UML object oriented analysis/design methods for the DTC enhanced RDF tracking system. The analysis and design was central to the overall effort and provided system-level cohesion for ARM processor, DSP, beacon transmitter, and TCP/IP connected PDA. Authored UML artifacts, protocol specs, and ICDs. Contributed the most significant body of C++ code, while managing PDA contract development, and providing group leadership.

Senior Engineer: Under Secret clearance, developed C++ enhancements for MTI tracker. The enhancements allowed data from multiple radar platforms to be used during tracking. Multi-platform tracking was demonstrated in a live mission using data from U2 and JSTARS. Developed a UML object model for the legacy tracker and promoted UML usage within the company.

Senior Software Engineer: First software engineer hired to design and implement in-vehicle, mobile, real-time tracking products. Working with hardware engineers created the system design for combined Radio Direction Finding (RDF) and GPS tracking products. Innovations include live data recorder, off-line replay, software signal filtering, statistical analysis and heuristic modeling techniques to address data uncertainty associated with RDF tracking. Developed a touch-screen GUI for in-vehicle operation.

• Used UML to design and MFC/C++ to implement tracker product. Implementation was completed on schedule and quickly attained high-reliability goals and exceeded expectations.
• Developed many protocols for RF communication, modem communication, and device programming. Protocols were implemented in Java, C, C++ and in firmware.

Principal Application Engineer: Provided custom mission-critical software and system solutions for RSA Security's largest ACE/Server customers. Listened to clients, analyzed core requirements, then proposed, designed, implemented, and documented solutions. Managed multiple contractor projects while implementing internal projects. Position required skills in engineering, management, marketing, field sales, negotiation, and customer relations. Created new system administrative model for the ACE/Server that was the basis for RSA's Professional Services business. Received stock option bonus for performance.

• Enhanced system architecture with an API toolkit layer that abstracted both encrypted structures and SQL queries. Developed the toolkit as a C lib, a Tcl script language extension and a sockets-based RPC running on four UNIX platforms and NT. Created a Java API prototype
• Teamed with engineering and developed an innovative enhancement to the toolkit in support of critical customer requirements. The on-time implementation resulted in making several million-dollar deals.
• Worked with RSA Labs scientists and developed a security model using MD for RSA's first Web-based administration tools.

Senior Project Engineer, Project Engineering Center (PEC): Developed rapid time to market medical systems and applications on Microsoft and OS/2 platforms using C, and C++. Recognized by management for producing high quality, supportable products. Versed in FDA test planning and ISO 9000 practices.

• Conceptualized and implemented a multi-threaded, client/server Data Bridge that passed real-time data from Named Pipes to IP sockets. Innovative design was key to the reuse of existing products and code. Project completion was rapid, and production quality. The project gave TCP/IP access to HP proprietary patient monitor network and was the basis for one of the PEC's most historically significant products.
• Represented HP at an international medical instruments session and delivered a panel presentation on "Enhanced Patient Monitor Alarm Notification".

Software/Project Engineer: Conceptualized and developed in-house UNIX workstation, PC-based applications. Optimized designs with considerations for UI, training, administration, portability and customer impact. Resulted in enhanced delivery of services. Received "Contributor of the Quarter Award" Q3 1992.

Knowledge Base Engineer: Designed, managed and implemented a Knowledge Base (KB) system prototype to assist in software support and troubleshooting while reducing Response Center costs. Presented at 1988 AAAI and published article "Help for Software Support" in AI Review 1988. Panel member on expert systems at EWC 1989.

Diagnostic Engineer: Key contributor of four-member team established to set diagnostic group test strategy. Designed and developed numerous on-line/off-line CPU, co-processor and memory diagnostics. Required deep knowledge of computer architecture, including RISC, CPU, MMU, DMA and buses. Created an innovative CPU cache technique for MMU testing. Received Stock Award and early promotion.

Associate Engineer: Senior member of micro-code development team, responsible for system/module design, real-time specification, coding on AMD2903 bit-slice graphics engines. Received early promotion.

Instrumentation Technician: Technical member of Space Positioning group providing 3D/telemetry data for NASA, Air Force, and contractor test flights. Received Secret clearance and honorable discharge.
