Project details
I will build a fully custom Retrieval-Augmented Generation (RAG) pipeline that makes your AI system smarter, faster, and more accurate. Using Vector Databases like FAISS and Weaviate, I create end-to-end solutions that help you search, index, and understand your private data with precision.
What you will get
• Custom RAG pipeline built for your exact use case
• Vector database setup using FAISS or Weaviate
• Chunking, embedding, indexing, and fast retrieval
• Integration with OpenAI, GPT-4/5, HuggingFace, LangChain, or LlamaIndex
• Secure ingestion of PDFs, Docs, text, or website content
• Real-time or batch retrieval workflows
• API integration for your app or chatbot
• Optimization for speed, accuracy, and memory usage
• Deployment on cloud (AWS, GCP, Azure) or local server
You get an AI engineer who builds clean, scalable, and production-ready RAG systems. I focus on real performance, not theory, so your system works smoothly in real life.
If you want a powerful RAG pipeline that understands your data, I am ready to build it.

Working with Muhammad has been an excellent experience from start to finish. He is professional, responsive, and clearly committed to delivering high quality work. Communication was clear and consistent throughout the project — he asked smart questions up front, provided progress updates without being asked, and was always quick to respond when I had feedback or revisions.
Muhammad delivered exactly what I needed, on time and to a very high standard. He was flexible when the scope evolved, offered helpful suggestions based on his expertise, and never hesitated to go the extra mile to make sure everything was right.
I would not hesitate to hire Muhammad again for future projects and I highly recommend him to anyone looking for a reliable, skilled, and trustworthy freelancer on Upwork.
