Aisha Z.

LLM Engineer | RAG Systems Developer | AI Automation Specialist

I design and build AI-powered applications that transform unstructured information into intelligent, searchable, and actionable systems. My focus is on Retrieval-Augmented Generation (RAG), LLM integrations, and domain-specific AI workflows where accuracy, structure, and reliability are critical. With a background in nursing, technical research, and AI-focused content development, I specialize in building systems that combine real-world domain knowledge with modern large language model capabilities. I work on AI applications that don’t just generate text, but retrieve, reason, and respond using verified knowledge sources. My core strength lies in bridging domain expertise (especially healthcare and research-heavy fields) with AI engineering, enabling the development of systems that are both technically sound and contextually accurate. I build solutions such as: RAG-based question answering systems over documents (PDFs, medical literature, knowledge bases) LLM-powered research assistants with citation-backed responses AI content intelligence systems for SEO, summarization, and structured knowledge extraction API-based AI automation tools for workflows and data processing
