Etisam Ul Haq
Over deze dienst
Most AI chatbots answer from general training data.
A properly built RAG system retrieves accurate,
sourced answers from your actual documents
with full source citations.
I build RAG systems and knowledge base chatbots
designed for production, not demos. Whether you
need a simple document chatbot or a full enterprise
RAG pipeline, I build it end to end.
What you get:
- Document ingestion pipeline
- Vector search with Pinecone or pgvector
- Source citations in every response
- FastAPI backend with REST endpoints
- PostgreSQL and vector database integration
- User authentication and role-based access
- Docker deployment setup
- Full source code and documentation
Use cases I cover:
- Internal company knowledge bases
- Legal and compliance document search
- Customer support automation
- Document intelligence platforms
- Research and analysis tools
Tech stack:
Python, FastAPI, LangChain, Pinecone, pgvector,
PostgreSQL, Docker, OpenAI, Anthropic Claude
Message me before ordering. I review every project
to ensure accurate scoping and delivery.

Veelgestelde vragen
What document types do you support?
PDF, Word, plain text, web pages and most common formats. Let me know your specific format before ordering and I will confirm compatibility.
How accurate are the answers?
Accuracy depends on document quality and structure. I use hybrid retrieval strategies to maximize relevance. I will be honest if your documents are not suitable before work begins.
Which vector databases do you work with?
Pinecone, pgvector, Qdrant and Weaviate. I recommend the best option based on your scale and budget.
Can this handle large document volumes?
Yes. Standard and Premium packages are built for multi-document, high-volume use cases with proper chunking and indexing strategies.
Do you provide full source code?
Yes. Complete source code with documentation is delivered in every package.
Can this integrate with our existing platform?
Yes. I design APIs specifically for integration with existing systems, CRMs and third-party services.
Is deployment included?
Standard and Premium packages include Docker deployment setup. Cloud deployment on AWS, GCP or Azure can be added as an extra.
What is your revision policy?
Revisions cover the originally agreed scope. New document types or features after delivery require a separate order.
Do you sign NDAs?
Yes. If your project requires an NDA I will sign one before work begins.
My project is more complex than premium. Can you handle it?
Yes. Message me before ordering. I create custom offers for larger or complex scope projects with accurate timelines.
