What I'm looking for

I want to build production-ready LLM systems—especially RAG and conversational AI—where I can ship real features, improve retrieval and prompts, and iterate quickly. I’m open to remote work and value hands-on experimentation.

I’m a self-taught LLM engineer with hands-on experience building and deploying production AI applications. I focus on LangChain-based systems, RAG pipelines, and LLaMA 3.3 to turn real-world problems into working products.

My work includes two live projects: an AI study assistant for Nigerian exam students and a document-chatbot platform. For the tutor, I implemented a RAG pipeline over a custom past-questions knowledge base with multiple study modes (quiz, explain, past questions, summary, Q&A), and used mode-specific prompt templates plus session-based chat history and a live score tracker.

For the chatbot, I built an end-to-end PDF ingestion and retrieval workflow (chunking, embeddings, vector storage, retrieval, and grounded LLM responses). I also added 5 switchable AI personas, adjustable temperature controls, and deployed publicly via Streamlit with Groq API integration for frictionless access.
