Multidisciplinary engineer with experience in embedded systems, backend development, robotics, and cybersecurity. I combine a strong academic background in applied physics and nanomaterials with hands-on engineering practice in both hardware and software domains. At SkyLab UA, I worked on the UGV Sirko-S1 combat robotic platform, developing embedded software for STM32/ESP32 microcontrollers. I integrated sensors, GPS, IMU, cameras, and wireless modules (LoRa, Wi-Fi, Bluetooth), optimized telemetry, and implemented navigation algorithms and actuator control. I used protocols like MAVLink, SBUS…

Integration and connection of the E-ink screen

Personal 56 USD

Oleksandr successfully completed the task, despite the fact that the task turned out to be much more complex than expected.

During the work, significant difficulties arose, as the manufacturer sent a board with the wrong firmware, and there was no ready driver that would work with this screen size and our configuration. After correspondence with the manufacturer, Oleksandr decided to reflash the board himself and write the driver almost from scratch, which he successfully did.
