Member of a team developing firmware for ultra-low power wireless sensor nodes (WSNs) that monitor the condition, environment and location of freight railcars. https://www.amsteddigital.com/Responsibilities:• Designed & coded Bearing Condition Monitoring (BCM) firmware that acquires wheel bearing temperatures via a network of WSNs mounted upon one or more railcars. The firmware generates alerts when abnormal conditions are detected.• Designed & coded ISO/IEC 18000-3 communications stack that provides contact-less half-duplex communication via RFID.• Designed firmware architecture & coded supervisor firmware for a Wheel & Bearing Monitoring System (WBMS) that monitored bearing acoustics and temperatures.• GNSS consultant, providing GNSS acquisition and impairment expertise to all management levels.• Designed & coded drivers for thermocouples and audio microphones.• Conducted internal Quality Audits to ensure compliance with ISO 9001:2015

Made significant contributions to SEL’s 20% per annum growth rate, as Software Lead for many innovative new products across multiple product lines. https://selinc.com/company/sel-about/Software Lead for the following product developments:• SEL-2407 GNSS Clock. Designed and coded the RTOS and application software in C. This product uses Xilinx Microblaze soft processor that formed the platform for a commercially successful range of clocks. https://selinc.com/products/2407/• SEL-2523 & SEL-2533 Annunciator Panels. Created the product architecture from an existing hardware and software platform. Designed and coded new application software in C++. https://selinc.com/products/2523/• SEL-3031 Serial Radio Transceiver. Designed and coded the I/O and radio driver software in C++. This product provides radio access to many SEL products. https://selinc.com/products/3031/• SEL-2664 Field Ground Module. Designed and coded the RTOS and application software in C. This product supports SEL Generator Relays. https://selinc.com/products/2664/

As Senior Software Engineer in the Automotive and Industrial Electronics Group, designed and coded real time embedded software for several automotive customers. • Designed and coded On Board Diagnostics and fault logging software, (in C), for MINI Body Controller• Wrote System Design and Software Design Procedures required to achieve CMM Level 3

Independent Software ConsultantIn a series of contracts for multiple customers, (mostly in the automotive industry), designed and coded Real Time Operating Systems (RTOS) and application software for Electronic Control Units (ECU). All software was written and tested to stringent automotive production standards, with some applications being safety critical. Software was coded in C and/or assembler.Customers and projects included:• BMW – Land Rover. Specified, designed and coded the RTOS for the Discovery II active suspension system. All software modules were safety critical and written in assembler, so extensive use was made of defensive programming techniques, peer reviewing, and formal testing methods to prove the safety of the design.• BMW – Land Rover. Designed and coded all hardware driver software in assembler for K series Engine Management ECU.• Ricardo plc. Designed and coded, (in C), the RTOS for an “instrumentation standard” Engine Management ECU used for calibrating Gasoline Direct Injection (GDI) engines. GDI engine control functions were implemented in MATLAB Simulink and transmitted via CAN interface to the ECU.• Pilkington Optronics. Designed and coded, (in C), all the RTOS, hardware driver, and application software that controlled the optical scanning test equipment for the Eurofighter Typhoon Forward Looking Infrared (FLIR) subsystem. It simultaneously controlled a high-speed stepper motor (at up to 10,000 steps/second) and a brushless DC motor.• MISRA-C:1998 “Guidelines for the use of the C Language in Vehicle Based Software”.
