About this gig

Please contact me before ordering to discuss your requirements.

Stop settling for fragile scripts. I build robust, production-ready AI systems combining modern LLM architectures, scalable FastAPI backends, and responsive React/Next.js interfaces.

What I Deliver:

  • Production RAG Pipelines: Advanced document retrieval (PDF/DOCX/CSV) using hybrid search, re-ranking, metadata filtering, and vector databases (pgvector, Pinecone, Qdrant) with hallucination guards.
  • Autonomous AI Agents: Multi-agent workflows with LangChain, LangGraph, and LlamaIndex capable of tool calling, web scraping, and database execution.
  • FastAPI Backends: Async REST APIs, WebSockets for token streaming, JWT auth, background tasks, and Docker deployment.
  • React Frontends: Modern UIs featuring streaming chat, dashboards, file managers, and citation viewers.

Tech Stack:

  • Frontend: React, Next.js, TypeScript, Tailwind CSS
  • Backend: FastAPI, Python, WebSockets, Docker
  • AI Orchestration: LangChain, LangGraph, LlamaIndex, OpenAI, Claude
  • Vector Stores: PostgreSQL (pgvector), Pinecone, Qdrant, Redis
