I build computer vision and robotics systems that work on real hardware - not just in a Jupyter notebook. Over the past 6 years I've taken AI systems from research idea to physical deployment: a sensor-fusion navigation system published at IEEE ICIICE 2026 (99.9% regime-classification accuracy, 63.9% lower trajectory error under GPS denial), a fully 3D-printed humanoid robot (Jazari) with integrated perception and conversational AI, and a precision-agriculture weeding robot published in MDPI Machines. I've also optimized computer vision pipelines to run in real time on constrained edge hardware (Jetson Nano) for production ADAS use. What I can build for you: - Computer vision: object detection, tracking, segmentation, OCR, pose estimation (OpenCV, PyTorch, TensorFlow) - Robotics & autonomous navigation: ROS, sensor fusion (LIDAR/GNSS/IMU), SLAM, path planning - Edge AI & embedded deployment: Jetson, STM32, ESP32, Raspberry Pi - End-to-end: from a working prototype to a documented, production-ready pipeline I work directly, hands-on - no hand-off to a black-box team. If you need someone who can take a computer vision or robotics idea from concept to a working system on real hardware, let's talk about what you're building.

I’m a robotics engineer with hands-on experience in drones, ground robots, and robotic software. I’ve worked on projects ranging from UAV swarming and autonomous navigation to SLAM, path planning, and control systems. Most of my work involves ROS1/ROS2, PX4, Ardupilot, and LiDAR-based mapping, but I’m comfortable jumping into anything that involves robotics hardware or software. I’ve built and tested drone swarm communication systems over LTE, integrated advanced SLAM algorithms like A-LOAM and LIO-SAM, and developed both PID and MPC controllers for precise movement. I also work with simulation tools like Gazebo, Rviz, MoveIt, and have experience with embedded platforms such as Jetson Nano, Raspberry Pi, Arduino, and STM32. If you need help with robotics simulation, drone development, mapping/localization, or control systems, I can take your idea from concept to working prototype. I prefer practical, working solutions over theory, and I keep communication clear and direct throughout the project.
