Project details
Most RAG systems fail because they retrieve the wrong information, hallucinate answers, or lack proper citations. The issue is usually the retrieval architecture—not the AI model.
I build production-ready RAG systems that deliver accurate, grounded answers from your documents, knowledge base, website, or database using GPT, Claude, Gemini, and open-source LLMs.
What I can build:
• RAG pipelines for PDFs, documents, websites, and databases
• Vector database integration (Pinecone, Qdrant, Chroma, Weaviate)
• Hybrid search, reranking, and metadata filtering
• Source citations to reduce hallucinations
• API integration with chatbots and business applications
• Secure cloud or private deployment
I've built enterprise document intelligence systems, including a legal query engine for 100,000+ case records and AI-powered knowledge assistants trusted for production workloads.

AI Prompting & Conversation System Audit
It's rare to find a freelancer these days that is legitimately an expert in what they do. Abdur is trustworthy, reliable and easy to work with. He's very fair and communicates his thoughts/intentions well. If you are working on a project that falls into his wheelhouse, I would suggest giving him a try and see the difference.

Python Developer Needed for Titan AI Core Development
This man is truly remarkable. After getting the description wrong, he worked an hour on it, an hour I can’t take back, but still he gets out of his way to do a project he wasn’t meant to do without charging extra. Truly amazing guy, recommend highly.

Job Success
Lahore, Pakistan - 6:11 pm local time
Recent work: Head of Development at Agentive, an AI-powered B2B revenue platform. Technical Lead at Redo, building enterprise RAG systems for justice-sector data. Built a GoHighLevel CRM and AI qualification system for a real estate business, including speed-to-lead automation and AI-qualified buyer/seller pipelines.
Core work:
- AI Agents & Multi-Agent Systems (LangGraph, CrewAI, AutoGen)
- Retrieval Augmented Generation (RAG) & Agentic RAG
- Business process & CRM automation (n8n, Make, Zapier)
- Conversational AI, chatbots, AI voice agents & custom AI product development
- AI SaaS platform architecture and development
Stack: OpenAI (GPT-5, GPT-4o), Claude, Gemini, Llama 4, LangChain, LangGraph, LlamaIndex, MCP, Python, FastAPI, Django, PostgreSQL, Pinecone, Qdrant, n8n, Make, GoHighLevel, Twilio, AWS/GCP/Azure, Docker, Kubernetes.
Clients usually come to me needing more than an API integration bolted onto a product or a CRM nobody maintains: someone who can own the technical side end to end, make architecture decisions, and ship something reliable enough for production.
If that's what you're building, I'd be glad to talk about your project.
