Aleksei B.

Senior Embedded Firmware & Hardware Engineer with 10+ years of hands-on experience in microcontroller development. I specialize in full-cycle product development — from schematic design and PCB layout (KiCad) to production-ready firmware and post-launch support. My main platforms are STM32, ESP32, and nRF52. I work with bare-metal and FreeRTOS in C/C++, CMake/GCC build systems, and communication protocols (UART, SPI, I2C, USB, Ethernet/LwIP, BLE, IEEE 802.15.4). I also implement secure data transmission with mbedTLS. I take full ownership of projects: I cover technical risks, debug complex issues, and deliver reliable solutions ready for mass production. One of my biggest achievements is the Baxi Ampera Plus electric boiler — a mass-produced device sold in multiple countries. I refactored a large legacy firmware codebase (Keil → CMake/GCC + CI/CD), reduced graphics library by 4000+ lines, and significantly improved maintainability and reliability. Other notable projects: Wireless sensor networks for spacecraft transport containers (IEEE 802.15.4) Sensor nodes for UAV systems (STM32L4 + nRF52, BLE) HVAC thermal monitoring systems with BLE and TLS USB-HS CDC implementation on TI AM243x 1inch Hardware Wallet I prefer modern CMake-based builds and have experience with Zephyr RTOS. Always focused on low-power optimization, reliability, and bringing products from prototype to commercial success. Available for both short-term critical tasks and long-term development contracts. I’m committed to minimizing client risks and delivering working, production-ready solutions.
