Lead Embedded Linux Engineer

Skilled and self-organized embedded Linux developer with 10+ years of engineering experience in the electronics industry. I provide the high quality design of firmwares with reliable configurations for your custom device or a single board computer. Passionate about designing devices for telecommunications, an automation, robotics solutions and other industrial control and monitoring systems with Yocto or another embedded Linux distribution. Complex problems with complex hardware is what I take on. Technologies I work with includes: * Yocto, Buildroot, OpenWrt and Armbian embedded Linux build systems, * STM32MP157F, Odroid XU4, Nano Pi, Orange Pi, Beaglebone Black single-board computers and development boards, * Jetson TX2, Jetson Nano, Jetson AGX Xavier single board computers with CUDA toolkit, * Allwinner H3/H5 and Tegra series SoCs, * configuration and device-tree customization for various peripheral devices, * C and C++ programming for Linux environment, Linux modules development, * Python programming for build systems and applications running on embedded Linux, * Robot Operating System (ROS) configuration and nodes development for navigation, SLAM and trajectory planning, * Qt framework and libraries, * QEMU emulator for various system architectures, * OTA solutions with Mender and other systems. Embedded Linux application development can include: * machine vision algorithms with OpenCV (C++, Python), * signals and image processing algorithms, * Boost C++ library, NumPy, SciPy Python libraries. I can help with hardware design for embedded Linux systems: * custom carrier board design for Jetson series boards, * Raspberry Pi hats custom design, * custom single board computer (SBC) design. And for microcontroller based devices: * firmware development for STM32,ESP32,ATmega32, CC13xx/26xx MCUs, * electronics and PCB design for IoT devices and interface extension, * power consumption optimization solutions. Electronics design can be done in Altium Designer or KiCAD. I'm looking forward to doing business with you!
