Designed and developed new embedded software for a High-Speed Money Counter and Currency Scanner machine based on an ARM platform and Linux RTOS. Supported engineers in all disciplines of product life cycle, including requirements, design and test.• Developed calibration software to normalize currency denominating and counterfeit detection sensor response across multiple machines. • Designed Ethernet-based client-server style software for a Windows PC data analysis application used to collect and analyze sensor data. This tool aided in debugging sensor issues and shorten development time.• Architected and designed proactive maintenance software used to monitor currency defects, machine motor life and battery life to help reduce customer site field support visits.• Shorten development time by implementing a test bed, using Google Test, to verify software application methods prior to hardware availability.• Created Windows Presentation Foundation (WPF) applications to generate and modify XML style application configuration files for a currency scanning and counting machine.• Designed and developed software for a test fixture used to test hardware functionality of a currency scanner and counting machine’s main CPU board. This software was used by board build house technicians to verify the board’s functionality after assembly.

Designed and developed new features and provided maintenance of embedded software across multiple hardware platforms and RTOS’s. Supported engineers in all disciplines of product lifecycle over several software releases, including requirements, design, code, and test reviewsOptimized signal quality allowing customers to reuse existing network by collaborating with optical engineers to develop and implement a real-time, feedback control loop algorithm.• Shortened development time by creating C++ hardware simulation software, that allowed application developers to test device drivers when hardware wasn’t available.• Designed and implemented several modular C++ device drivers for devices with I2C, SPI, UART and MDIO interfaces as well as FPGAs and ASIC’s for multiple Linux multi-threaded applications.• Allowed cost-reduction hardware upgrade without full software upgrade by developing a scalable, client-server RPC abstraction layer. Utilized UML modeling to create functional partition interfaces.• Reduced customer expense by developing real-time firmware upgrade algorithms, which allowed customers to upgrade firmware on-site.• Provided timely failure analysis and resolution of hardware-software integration issues found during product pre-release and customer related issues found during product deployment.

Designed the following low-level C and assembly software drivers for two versions of a MPEG Video Set Top-Box decoder. - Serial port, parallel port, interrupt controller, flash programming, Ethernet card, graphics card, periodic interrupt timer, memory tests, Philips Digital RFTuner, stereo/SAP decoder, and an analog device's video encoder.Utilized SingleStep Simulator and EST VisionICE emulator during initial integration of software drivers. - Wrote boot software for top boxes; created test software to integrate and test hardware/software.Developed PC software utility used to download and program flash applications into Set-top box's flash memory.Responsible for troubleshooting, coordinating and supporting various versions of MPEG Video Set-top boxes Decoders during 1000+ piece production runs and field returns
