John Martinez - Senior Embedded Systems / ASIC / Hardware Engineer | 30+ Years | Embedded Linux (Yocto), C/C++, Firmware, BLE, PCB, RTL, Mixed-Signal Design
About - Senior Embedded, ASIC, and Hardware Engineer with 30+ years of hands-on experience designing, developing, validating, and manufacturing embedded systems and ultra-low-power ASICs. I specialize in embedded Linux (Yocto), C/C++, firmware, system bring-up, mixed-signal electronics, BLE communications, hardware diagnostics, and ASIC/RTL logic design.
<< ASIC - Application Specific Integrated Circuit >>
<< PCB - Printed Circuit Board >>
<< BLE - Bluetooth Low Energy >>
<< OTA - Over-the-air update >>
I was the principal ASIC architect behind multiple FDA-cleared medical devices for BioElectronics (ActiPatch®, RecoveryRx®), where I designed custom digital logic engines, ultra-low-power waveform generators, discrete timing structures, and test harnesses used to evaluate bare-die silicon before QFN packaging.
My background spans ASIC development, embedded firmware , board-level design, mixed-signal debugging, RF/EM field testing, and complete product lifecycle support. I create solutions that reduce power consumption, increase reliability, and accelerate time-to-market.
Experience - Designed custom embedded Linux (Yocto) systems, BSP modifications, device-tree configurations, and board bring-up workflows.
Developed C/C++ firmware, Python diagnostic tools, and automated test harnesses for embedded platforms and BLE modules (e.g., JDY-23).
Created mixed-signal PCB designs, power-delivery modules, custom coils, analog front-ends, and hardware prototypes for research groups.
Implemented Bluetooth BLE data pipelines , OTA update frameworks, and laptop-to-device communication tools (Python + BLE).
Collaborated with medical and research teams ( Electrome , Forward Edge-AI, startup R&D groups) on advanced sensing systems, waveforms, energy delivery devices , and magnetocaloric prototypes.
Produced technical documentation, LaTeX engineering reports, provisional patent drafts, block diagrams, and system architecture specifications.
Bioelectronics Corp. - Senior Engineer
** Senior Embedded / ASIC / Hardware Engineer
** Lead architect and designer for ultra-low-power ASICs used in FDA-
cleared medical devices (ActiPatch®, RecoveryRx®).
Designed discrete logic engines, low-power waveform generators, ring counters, dividers, and timing structures subsequently implemented in silicon via Qx Micro Devices (Shenzhen) and Taiwan foundries.
Developed and tested bare-die silicon using “cat-whisker” probing prior to final QFN package integration.
Created embedded firmware, manufacturing test tools, PCB designs, and hardware validation equipment for commercial devices.
Performed signal integrity analysis, low-noise analog design, RF/EM field testing, and power optimization for long-duration medical devices.
Supported full product lifecycle, including prototyping, validation, reliability testing, and high-volume manufacturing.
Skills
** Python (programming language)
** C & C++ programming language
** Firmware development
** Embedded Linux & Embedded Systems
