You will get a build production-ready RAG system for your SaaS or data
Rising Talent
Project details
I will build a production-ready Retrieval-Augmented Generation (RAG) system for your SaaS or internal data platform. This system transforms your data into actionable AI-powered responses, chat interfaces, and API endpoints, designed to be scalable, reliable, and fully production-ready.
Services Include:
Data ingestion & processing: PDFs, Docs, APIs, Databases
Vector search & retrieval: Pinecone, pgvector, or similar
LLM integration: OpenAI, Claude, Gemini, or your preferred model
Smart retrieval & reranking: High-accuracy answers with hybrid or cross-encoder ranking
Multi-agent orchestration: Optional agents for advanced workflows
API & chat UI: Optional interface for internal or external users
Scalable Dockerized deployment with full documentation
Deliverables:
End-to-end RAG system connected to your data
Vector search + retrieval layer integrated with LLM
Optional multi-agent orchestration for workflow automation
API endpoints and chat interface if needed
Full documentation for deployment, usage, and future scaling
I specialize in LLM infrastructure, RAG pipelines, and AI system orchestration, delivering repeatable, scalable AI solutions that grow with your business.
