Added cellular communications capability to a satellite-based remote asset tracking device. Solely in charge of the end-to-end electronics and software design, leading a team of four to create a completely new communications path from the existing hardware to a web-based server display. This capability significantly increased value of the end product by introducing two-way transmissions, "urban canyon" reliability, and seamless integration with existing service offering.Significantly improved existing products. Enhanced GPS tracking algorithm to extend the battery life of product by 300% in non-optimal conditions. Supplemented existing firmware with fail-restore module to positively identify system freeze and restart application with no lapse in functionality. Designed, implemented, and tested changes to product firmware and hardware in less than 1 week to secure new customer and double product sales.Enhanced product development processes. Refactored existing code base to support multiple products by design. Incorporated high-fidelity energy consumption testing into development and release practices. Created triage and investigation portion of reverse logistics process to provide direct feedback into product life-cycle and ensure rapid resolution. Supported customer integration and certification activities including on-site assistance when needed. Championed independent open testing practices of products to supplement matrix procedural approaches.Contributed engineering expertise at every opportunity. Assisted all levels of engineering staff and project managers with problem identification and resolution activities. Coordinated parallel efforts of firmware, electronics, and industrial design teams to efficiently close on seamlessly integrated products. Independently cross-tested products to identify issues and find solutions. Created rapid prototypes of new concepts using existing products.

Developed widely deployed low-cost satellite asset tracking device as member of three person team. Completed first firmware release to production 6 months after effort started and achieved target active lifetime of 5 years using 3 AA batteries.Created all firmware, source architecture, and design processes for product. Responsible for source structure, program flow, execution environment, internal APIs, binary communication protocols, version control procedures, coding style guide, review processes, and requirements traceability. Additionally, created software interface control documents and designed all binary communication links including compressed satellite message structure and efficient protocol for the 802.15.4 local network.Tested flight software for the Space Technology Program's STPSAT-2 spacecraft. Designed and executed test procedures to verify and document operation of flight software system. Validated requirements compliance to meet the 5 month delivery deadline. Spacecraft on-orbit and functional since 19 November 2010.Led a team in research and development activities associated with a low-bandwidth high-availability communications system for LEO spacecraft. Developed business interest from customers and secured external funding for design. Identified key technologies needed to create a successful device and nurtured relationships with sole-source suppliers of the same.Assisted in hardware and software design of proof-of-concept and proposal systems, including an imaging and threat detection system for spacecraft, a nanosatellite class constant momentum gyroscope, and the NRO Colony II bus architecture.

Smoothly transitioned product development, ongoing design, and continuing engineering activities for all customers of Qubic Systems to engineering staff at Device Solutions.

Created equipment tracking and remote disable product. Synthesized detailed requirements including hardware, firmware, fail-safe, and over-the-air interface system components. Exceeded client expectations using clear written and verbal communication and understanding client vision of the desired product. Constructed prototype in less than 8 weeks and production-level design in 6 months.Facilitated systems integration effort including embedded firmware and server-side software as well as mechanical, electrical, and wireless interfaces. Designed HTTP-based communications protocol to enable low-risk rapid development and deployment. Conducted system, software, and circuit design reviews to reduce cost and development time by identifying design errors and specification conflicts.Managed complex interactions of desires from product subsystem development teams including parallel design paths of the custom enclosure and the electronic systems. Assisted in design of production flow processes and specification of functional test fixtures for manufacturing process.

Led state-wide multi-disciplinary student team in design and construction of nanosatellite. Blended off-the-shelf technologies and custom built solutions to meet timeline, fiscal, and human resource budgets. Successfully moved project from concept creation to fully functional engineering model in one year.Provided system design direction and advanced planning for integration of mechanical structures, electronic hardware, and software systems. Architected computing, communication, and sensing systems as modules to ease integration test process and facilitate reuse of components in future missions. Crafted communications protocol for on-orbit operations complementary to existing network infrastructure to create inexpensive global access network.Created procedures and system to facilitate the capture of high-quality documentation of the project. Regularly made presentations to technical and non-technical audiences including University Presidents, the funding organization Board of Directors, and the attendees of the 2007 IDEA Festival. Responsibly cultivated leaders to assume project ownership and maintain cohesive team structure during and after management transition.
