You will get Custom RAG Systems with Vector DBs, LLM Chatbots & Gen AI
Project details
I build custom Retrieval-Augmented Generation (RAG) systems that make LLMs smarter, more accurate, & context-aware using your private data. As an experienced AI engineer, I develop production-ready RAG pipelines that combine LLMs, vector databases, and semantic search for real-world business use cases.
I specialize in custom RAG pipeline development using Pinecone, Weaviate, FAISS, ChromaDB, & Elasticsearch, integrated wth OpenAI, GPT-4/5, HuggingFace, LangChain, & LlamaIndex. Each system is designed to retrieve the most relevant information before generation, ensuring reliable & factual AI responses.
My RAG solutions support PDFs, documents, databases, APIs, website content, with advanced chunking, embeddings, indexing, hybrid search, & metadata filtering. I build RAG systems for AI chatbots, enterprise knowledge bases, SaaS products, internal tools, research systems, and customer support automation.
Every solution is optimized for speed, accuracy, memory efficiency, and scalability, with optional API deployment, cloud setup (AWS, GCP, Azure), & secure access control.
If you’re looking for a reliable RAG expert, LLM engineer, or Gen AI developer who builds real, Let's Connect.
