Embedded Software Engineer • Real-Time Firmware • Cellular IoT & Wireless Systems
I build deterministic embedded software for resource-constrained, connected devices. My focus is on turning low-level system constraints into robust, production-ready behavior:
- System Architecture: Active Object design patterns, lock-free data structures (MPSC ring buffers), static memory allocation, and MISRA C:2012 compliance.
- Real-Time Firmware: RTOS (Zephyr, FreeRTOS, RTEMS) and bare-metal architectures in C/C++.
- Hardware Integration: Board bring-up, low-level driver development, and sensor fusion.
- Cellular & Wireless IoT: LTE, 5G, NB-IoT, and NTN integration, managing complex AT command flows, MBIM, and QMI.
Alongside my private architectural work, I actively contribute to the ZSWatch open-source Zephyr smartwatch ecosystem. My recent work includes:
- Implementing Hebrew Right-To-Left (RTL) notification rendering and font subsetting.
- Developing sensor fusion algorithms (IMU & barometric data) for step-tracking and elevation.
- Dynamic PMIC battery profiling for the Nordic nPM1300.
