Summary
🤩
RockstarPavel Kirienko is a seasoned software engineer with 13 years of experience specializing in real-time embedded systems, UAVs, and IoT, currently contributing at Zubax Robotics in Tallinn. He is a core maintainer of OpenCyphal and has deep expertise implementing Cyphal/CAN protocol stacks and low-level BXCAN driver interactions in C for safety-critical systems. Pavel’s work on PX4 integrated UAVCAN into the PX4 autopilot, adding ESC control and sensor bridges for GNSS, barometer, and magnetometer data—efforts that directly enable robust vehicle communication on popular open-source flight stacks. Known for meticulous memory management, error handling, and protocol marshaling, he combines systems-level rigor with practical engineering to ship reliable firmware. Colleagues benefit from his knack for untangling hardware-software interactions and surfacing subtle driver-level fixes that improve whole-system determinism.

PX4 Autopilot Software
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:27 reviews, 185 commits, 27 PRs in 2 years 11 months
Contributions summary:Pavel primarily contributed to the integration of UAVCAN, a CAN bus protocol, within the PX4 autopilot software. The contributions focused on the development of a UAVCAN node for the autopilot system. They implemented various aspects, including initial integration, ESC control, and sensor bridging (GNSS, barometer, and magnetometer). This work involved creating and modifying modules to support communication and control over the UAVCAN protocol.
