Building a custom computer vision application? Need an AI model that actually performs in the real world, rather than just looking good on a testing dataset? Hi, I’m Gebrecherkos. I help startups, researchers, and hardware teams design, train, and deploy high-performance Deep Learning and Computer Vision pipelines. Because my background is heavily rooted in autonomous robotics, I don't just build models—I build robust, lightweight systems that are designed to survive messy, real-time edge deployments. Whether you need to detect anomalies in medical scans, build a custom object detection pipeline, or optimize a neural network for real-time inference, I can bring your AI project to life. 🧠 CORE MACHINE LEARNING & CV CAPABILITIES: 🔹 Computer Vision & Image Processing: End-to-end pipeline development for Object Detection, Semantic Segmentation, and Image Classification. Building and fine-tuning custom CNN architectures (e.g., EfficientNet, ResNet) and U-Net models for binary/multiclass segmentation. Expertise in extensive data augmentation strategies for domain adaptation (blur, jitter, synthetic generation) to ensure models generalize to the real world. 🔹 Advanced Deep Learning Architectures: Designing complex Multimodal Data Fusion systems. Developing and implementing Graph Neural Networks (GNNs) for highly specialized classification tasks (e.g., medical skin lesion classification). Deep expertise in PyTorch and optimizing custom loss functions (Cross-Entropy, Lovász-Softmax) for edge-case accuracy. 🔹 Real-World AI Deployment (The "Robotics" Edge): Unlike pure data scientists, I know how to make AI interact with the physical world. Experience deploying ML models onto edge devices and integrating them with autonomous navigation systems (ROS1/ROS2, SLAM). Proven track record with complex datasets, including underwater Unexploded Ordnance (UXO) detection and highly imbalanced medical imaging. 🛠️ TECH STACK: PyTorch, Scikit-learn, Pandas, OpenCV, Matplotlib, ROS1/ROS2, Linux, Git. Let's build something intelligent. Send me a message with a brief description of your Computer Vision or Machine Learning roadblock, and I will provide a high-level technical approach on how we can solve it—no strings attached.
