Build custom advanced, graph & agentic RAG systems for your data
- Views 3
What you get with this Offer
What I build for £1,500 (5-day base):
✓ Advanced RAG — hybrid search, reranking, query rewriting, multi-step retrieval
✓ Graph RAG — knowledge graphs + vector search, captures entity relationships
✓ Agentic RAG — autonomous agents planning retrieval, using tools, multi-hop reasoning
✓ Up to 200 pages / documents ingested
✓ Production API + admin panel
✓ Source citations on every answer
✓ JWT auth + secure hosting + custom branding
✓ 2 revisions + 30 days support + 30-min handover call
✓ Delivery in 5 days
Pick your RAG type (or hybrid):
- Advanced — for teams whose basic RAG returned irrelevant answers
- Graph — for content rich in entity relationships (GraphRAG-style)
- Agentic — for complex multi-step queries needing reasoning + tools
Perfect for: SaaS founders building AI that works, companies whose basic RAG failed, AI teams needing graph knowledge, consultancies building agentic assistants, compliance/legal needing source-cited answers.
Process:
1. 15-min discovery call within 24h to scope the approach
2. You send documents, requirements, use case
3. I design, build, deploy
4. Live preview to test
5. 2 revisions + handover + 30 days support
Stack: Next.js · FastAPI · Qdrant / Chroma · Neo4j (Graph) · LangGraph (Agentic) · MongoDB · OpenAI / Groq. Architecture proven in my RAG Workspace portfolio.
NOT included (see extras): API costs (~£30–£60/month), hosting beyond 30 days, more than 200 pages, multi-tenant, SSO.
FAQ
Difference between advanced, graph, agentic RAG?
Advanced: hybrid search + reranking. Graph: entity relationships via knowledge graph. Agentic: agents planning multi-step retrieval. I recommend the right one in discovery.
Why not basic RAG?
Basic RAG fails on complex queries, relational content, multi-hop reasoning. These systems solve that.
Framework or scratch?
Hybrid — LangChain/LangGraph for orchestration, custom code where frameworks fall short.
Migrate my existing RAG?
Yes — message me with details and I'll quote.
Multi-tenant / SSO / audit logs?
Available as extras.

What the Freelancer needs to start the work
To get started, please send me:
• Documents to train on (PDFs, DOCX, or web URLs — up to 200 pages)
• Your use case — what kind of queries should the RAG handle?
• 3–5 sample queries you want answered well (helps me tune the system)
• Preferred RAG approach — advanced, graph, agentic, or hybrid (or open to my recommendation)
• For Graph RAG: entity types you care about (people, products, regulations, etc.)
• For Agentic RAG: tools or actions the agent should be able to take
• Logo, brand colors, fonts (for the UI)
• Your OpenAI or Groq API key (I can guide you through setup if needed)
• Preferred hosting region (UK / EU / US)
A 15-min discovery call within 24h of order is included to align on scope and recommend the right RAG approach.
