Hi, I'm Elkana Molson 👋

Embedded Software Engineer • Real-Time Firmware • Cellular IoT & Wireless Systems

🚀 What I Do

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.

🔄 Current Focus

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.
  • Check out my fork and ongoing PRs: elkanamol/ZSWatch

🧰 Tech Stack

  • Languages: C, C++, Python, Bash
  • Systems & RTOS: Zephyr, FreeRTOS, RTEMS, Linux (WSL2 / Ubuntu build environments)
  • Architectures: ARM Cortex-M, STM32, ESP32, x86
  • Connectivity & Protocols: LTE, 5G, NB-IoT, Bluetooth, Wi-Fi, MQTT, CoAP, LwM2M, UART, SPI, I2C, CAN
  • Tools & QA: CMake, GCC/G++, JTAG/SWD Debugging, Logic Analyzers, Unity/CMock (TDD)

📌 Selected Projects

  • Sierra LTE 5G Flasher
    Python, AT Commands | Automated firmware flashing and configuration workflow suite for Sierra Wireless cellular modules.

  • IoT Sensor Habitat Tracker
    C, STM32, FreeRTOS | Low-power embedded sensing and monitoring system.

  • μAT
    C, Bare-metal | Lightweight, zero-allocation AT command processing engine for embedded communication systems.

  • RTOS Dispatcher RT
    C/C++, STM32F7 | Priority-based real-time task dispatcher demonstrating deterministic scheduling concepts.

🤝 Collaboration & Interests

I’m always open to discussing:

  • Firmware architecture, Active Objects, and lock-free data structures.
  • Multi-agent AI workflows for local code review and MISRA compliance.
  • Low-power cellular IoT integration.
