I'm a Full Stack AI Engineer with hands-on experience building and deploying end-to-end ML and generative AI systems. I specialize in computer vision, NLP, and retrieval-augmented generation (RAG) using Python, TensorFlow, LangChain, and FastAPI. I've built and deployed a RAG-based contract analyzer with source-citation verification, a natural language to SQL tool, and a computer vision crop disease detector each shipped as a live, working product, not just a prototype. Let's build something real for your business.
