Category : Web development
I’m an AI Engineer with 6+ years of software engineering experience, specializing in Large Language Models, Generative AI, RAG, AI agents, and intelligent automation. I build production-ready AI applications using Python, FastAPI, OpenAI API, LangChain, LlamaIndex, vector databases, and modern cloud infrastructure.
I can help with AI assistants, RAG systems, document processing, semantic search, AI agents, customer support automation, AI-powered APIs, and integrations with existing business systems.
My approach focuses on reliable, maintainable solutions with secure APIs, well-structured backend services, evaluation workflows, and practical deployment. I can take an AI project from architecture and development through integration and production deployment.
