Professional Summary
Embedded systems engineer with strong hands-on experience in STM32-based platforms,
covering the full development cycle from hardware bring-up to production-ready firmware.
My background includes low-level firmware development in C/C++, real-time system design using
FreeRTOS, and integration of microcontroller peripherals and external devices. I have extensive
experience working with common communication interfaces (UART, SPI, I2C, CAN), analog and
digital signal acquisition (ADC, DAC), IMUs and GNSS/GPS-based systems.
I have implemented signal processing and computational algorithms on resource-constrained
MCUs and developed graphical user interfaces using TouchGFX on dual-core STM32 platforms.
In addition to firmware development, I have a solid understanding of digital electronics, schematic
design, and prototyping, which allows me to work effectively at the hardware–software boundary.
I regularly use both hardware and software debugging tools and am comfortable troubleshooting
complex system-level issues involving interaction between firmware, electronics, and external
devices.
I am primarily interested in remote work. If required, I am available for occasional on-site visits or
short-term stays to support integration, validation, or critical project phases. Currently based in
Zhytomyr, Ukraine, with a fully equipped home workspace and the ability to travel internationally
when required.
