Remy O.

AI/ML&Data Backend Engineer | Django, Node.js, LLMs, Computer Vision

I build production-ready AI/ML/Data backend systems using Python, Django, FastAPI, Node.js, LLMs, computer vision, vector search, AWS/GCP, Docker, and Kubernetes. I help teams turn AI prototypes into reliable APIs, data pipelines, and deployed products. My strongest work is at the intersection of machine learning and backend engineering: LLM applications, computer vision and data pipelines, OCR systems, data-heavy APIs, model deployment, and scalable backend services using Python, Django, FastAPI, Node.js, NestJS, PostgreSQL, vector databases, AWS, GCP, Docker, and Kubernetes. I can help you with: • Building AI-powered backend systems from scratch • Integrating OpenAI, Hugging Face, LangChain, LlamaIndex, or custom ML models into real products • Creating Django, FastAPI, or Node.js APIs for AI/data applications • Designing RAG systems, vector search, document intelligence, and structured-output LLM workflows • Training, fine-tuning, evaluating, and deploying ML models • Building computer vision and OCR pipelines with PyTorch, TensorFlow, JAX, OpenCV, and Transformers • Improving model latency, reliability, accuracy, and production monitoring • Creating cloud-native ML infrastructure on AWS or GCP • Cleaning up unstable backend systems, tests, CI/CD, and deployment workflows Recent work includes production NLP, computer vision, Data pipelines, multimodal AI systems, OCR models, document-processing tools, AI dashboards, real-time inference services, and large-scale ML pipelines. I have worked on systems involving sub-100ms latency targets, 4× inference throughput gains, 20–40% model quality improvements, OCR accuracy improvements, and cloud deployments serving high-volume workloads. Unlike many ML engineers, I do not stop at notebooks. I build the APIs, services, databases, tests, deployment pipelines, and monitoring needed to make AI useful in production. Core stack: Python, Django, FastAPI, Node.js, NestJS, TypeScript, PostgreSQL, MySQL, MongoDB, SingleStore, FAISS, Pinecone, PyTorch, TensorFlow, JAX/Flax, OpenCV, Hugging Face, LangChain, LlamaIndex, OpenAI API, AWS, GCP, Docker, Kubernetes, CI/CD. Good fit if you need someone who can understand the model, the backend, the data, and the product requirements in one conversation.
