Aliaksandr Kavalchuk
I`m a seasoned Firmware Engineer with over a decade of hands-on experience in embedded systems development, microcontroller programming, and low-level debugging. My professional journey spans full-cycle product development — from schematic design and PCB layout to firmware architecture and production-ready code — across diverse industries, including industrial automation, wearable technology, and data storage.
I have contributed to mission-critical products for companies such as Grundfos (industrial dosing pumps), KIOXIA (enterprise SSDs), and numerous IoT and consumer electronics startups. I`m proficient in C/C++, Python, and RTOS/Linux-based systems, with deep expertise in protocols like UART, SPI, I2C, and 1-Wire, as well as hardware debugging via JTAG, SWD, and logic analyzers.
Beyond my engineering work, I`m an active technical writer. My publications include the books “Wired Protocols in Embedded Systems” and “Diving into JTAG”, along with in-depth articles featured on platforms like Memfault, PlatformIO Labs, and Medium. My goal is to demystify complex technical concepts and explain them in a clear, practical manner.
