Summary
🤩
Rockstar🎓
Top SchoolAlexander Khromykh is a Senior R&D Engineer with over two decades of embedded systems experience and five years in his current role at Nordic Semiconductor, specializing in low-power wireless stacks and MCU/FPGA firmware. He has deep hands-on expertise in C/C++, assembler, GNU/IAR/Keil toolchains, and peripherals (USART, I2C, SPI, USB) across AVR, ARM7 and Cortex-M platforms, and has led teams to deliver IEEE 802.15.4 and Zigbee solutions. At Luxoft he designed architecture, test systems and managed a team to produce compliant 802.15.4 stacks for nRF52840, and his open-source contributions enhance Bluetooth Mesh in prominent projects like Zephyr and nRF Connect SDK. Comfortable at the intersection of protocol design, low-level drivers and product delivery, he also brings FPGA experience (Xilinx) and a practical background in bootloaders, DFU and persistent storage for constrained devices. Notably, he blends long-term vendor and standards work with a recent focus on improving mesh reliability and DFU mechanisms in widely used RTOS ecosystems.
