Responsible for guiding four teams into productization: embedded systems, algorithms, hardware and manufacturing, and embedded CI/CD.Currently, leading the engineering team responsible for developing a rail defect detection system called Focus.Personally responsible for architecting, integrating next generation safety critical embedded platform for rail navigation in transit systems. I prototyped an embedded platform including mechanical, electrical, firmware and safety-critical PikeOS hard-real-time operating system (RTOS) architecture to inform the full product development effort at various CENELEC stages. The prototype became the basis for the formal product architecture. Prototype and product is based on the NXP i.MX 8x quad-core ARM A35.Developed embedded software architecture for mixed-criticality PikeOS RTOS implementations which integrates various sensor types such as IMU, GNSS/INS and UWB RF systems and integrates with train controllers (CBTC/OBCU devices.)Devised strategies to marry modern software development with safety-critical V-model CENELEC standards, verification and validation. Test automation, embedded devops, and embedded security are always key elements in my designs.
