I build practical AI tools that solve real problems — RAG-powered chatbots, LLM applications, document-intelligence systems, and AI-driven automation that actually ships. I'm an AI developer with a strong foundation in machine learning, Python, and modern generative-AI frameworks, backed by 20 years as a technical professional and computer science educator. That combination means I don't just write code — I understand workflows, assessment, and how people actually use a tool, so what I build gets adopted, not abandoned. What I can build for you: RAG (Retrieval-Augmented Generation) systems — chat with your PDFs, documents, and private data using LLMs, vector databases, and semantic search AI chatbots & assistants — customer support, internal Q&A, and knowledge bots integrated with your tools AI-powered content & question generation — quizzes, exam banks, summaries, and structured content at scale Educational AI tools — AI-assisted grading, rubric-based evaluation, feedback generation, and learning analytics Python automation & data tools — data analysis, visualization, dashboards, and workflow automation A few things I've already built and deployed: A RAG PDF assistant using Groq, LLaMA 3.3, ChromaDB, and Streamlit for fast, context-aware document Q&A An AI grading and evaluation system with rubric-based scoring, feedback generation, and exportable reports AI quiz and question generators (live and in production use) My stack: Python, LLMs (LLaMA, GPT-family), RAG, LangChain-style pipelines, ChromaDB & vector embeddings, Hugging Face, Streamlit, prompt engineering, SQL, Pandas, and data-visualization libraries. I communicate clearly, ask the right questions before I start, and care about delivering something that works for your users. If you have a project in mind, send me a message — I'll tell you honestly whether it's a good fit and how I'd approach it.
