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.

I have a degree in Telecommunications Networks Engineering and also possess a minor in Data Science, both gained in university Pompeu Fabra. I have 8 years of experience with Python and about 2 years of experience with LLM. I have experience with RAG and Langchain, development of AI agents and FastAPI. I have extensive experience building end-to-end RAG pipelines. In my recent work at Revolut as an IAM InfoSec, I developed a data pipeline using the Jira API to extract access-request tickets, processing them via LLM-driven analysis (LangChain) for automated reporting. I am comfortable with the entire lifecycle: corpus preparation, embedding generation, and context assembly. I am a strong advocate for "clean code" (typing, testing, and packaging). My experience as a DevOps Intern at Arbolus and a SysOps Engineer at Vendo Services has given me a deep proficiency in Docker, CI/CD (GitHub Actions), and AWS (ECS, RDS, S3), ensuring that the AI applications I build are scalable, observable, and cost-effective. I have experience with auditing the ISO27001 standards which I gained during my stay at AQU Catalunya as well as IT Support at Arbolus. Also, as a SysOps at Vendo, I ensured our company not only to be compliant with ISO27001 standards but also with PCI DSS and GDPR standards. Also, my experience developing Ansible automation and complex configuration scripts aligns perfectly with your requirement for orchestrating services and managing back-office workflows via tools like n8n or Airflow. I did 2 personal projects: In the first one, I have successfully developed autonomous AI agents using LangChain and integrated them into conversational platforms like WhatsApp and Telegram via APIs. Also, I engineered a script for stock market prediction, trained it on Apple stocks and achieved an accuracy rate of 98.5%. I have a C1 level in English and Spanish. I also speak Russian, Catalan, Azeri and a bit of Ukrainian. You can find more information about my previous experience on LinkedIn and also feel free to check my Github (SH-SW). Fun fact, I play chess since I was 4. Being the national champion back in 2014-2015, my highest achievement was getting into top 10 of Europe in youth, with FIDE ELO 1861.
