I build secure and reliable LLM & RAG applications using Python, FastAPI, LangChain, LangGraph, Ollama, and vector databases.

I can help you with: • Custom RAG pipelines • Document Q&A systems • Local LLM integration • FastAPI backend APIs • Semantic search • AI guardrails and security checks • Grounding and response validation • ChromaDB-based retrieval

I focus on clean architecture, practical workflows, and solutions that are ready for real-world use.
