At Optonix, I developed and integrated support for ATI640S thermal imaging cameras, working across Device Tree, V4L2, sensor integration, and video pipelines. I also developed a Qt-based interface for camera configuration and thermal imaging.

As a freelance Embedded Firmware Engineer / Consultant, I architected an R&D telemetry system on an ARM Cortex-A53 embedded Linux platform and developed multi-threaded C applications for hardware data processing. My experience also includes Buildroot customization, RTSP video pipelines, and embedded firmware development.
