Project history
Providing high-end B2B engineering consulting, end-to-end hardware design, and complex embedded software architecture for commercial clients in the US and globally. Key focus areas include full-cycle contract hardware product development from initial architecture to factory-ready documentation, signal integrity optimization for high-speed digital interfaces and low-noise precision analog systems, and custom Embedded Linux and RTOS software development with cross-platform UI engineering and secure AWS cloud integrations.
Ported, optimized, and expanded a high-throughput, real-time data analytics software suite for industrial Distributed Acoustic Sensing (DAS) systems monitored along critical fiber-optic infrastructure. Engineered a cross-platform software abstraction wrapper for Jungo WinDriver, migrated PCIe DMA data pipeline from Windows to Embedded Linux, developed advanced DSP classification algorithms using FFTW, refactored the core application into a high-performance multi-threaded C++ system, and designed a dynamic real-time data visualization user interface.
Delivered end-to-end hardware engineering, low-level firmware initialization, and cloud-to-device infrastructure provisioning for flagship commercial products. Key projects included re-engineering the NVIDIA Jetson Orin NX Carrier Board for high-volume manufacturing cost optimization with PCIe Gen4 and USB 3.2 Gen2 routing on FR-4, STM32 bootloader firmware development, a custom industrial cellular IoT asset tracker using Nordic Thingy:91 (nRF9160, Zephyr RTOS), and AWS IoT Core and nRF Cloud deployment for secure device onboarding and telemetry.
