About this gig

I provide AI development services focused on building practical, production-ready applications powered by large language models (LLMs). My expertise includes developing custom AI chatbots, retrieval-augmented generation (RAG) systems, and knowledge graph-based solutions for real business use cases such as customer support, e-commerce, and content automation.

I can design and implement intelligent systems that integrate LLMs with structured data sources like MySQL or Neo4j, enabling more accurate, context-aware, and explainable responses. I also build automation pipelines for tasks such as product content generation, data processing, and workflow optimization using Python, prompt engineering, and agent-based architectures.

In addition, I have experience creating recommendation systems and semantic search applications that combine graph-based reasoning with modern AI models to improve performance and relevance. My goal is to help businesses reduce manual workload, improve decision-making efficiency, and deploy scalable AI solutions that go beyond simple chatbots and deliver real operational value.
