Sobre mí
I'm Amin Sharif, an AI Engineer specializing in RAG pipelines, LangChain, and LangGraph. With 5+ years of enterprise software engineering experience (C#.NET, Angular, FastAPI, Next.js), I now build production-ready AI assistants that turn documents into intelligent conversational systems.
My flagship project, Knowledge AI is a full-stack RAG-powered chatbot with hybrid retrieval, source transparency, and multi-model support (OpenAI + Ollama). I deliver scalable, accurate, and cost-efficient AI solutions for customer support, internal knowledge bases, and document Q&A platforms.
