About this gig
Are you ready to move beyond basic chatbots?
I am a full-stack AI engineer specializing in building autonomous AI Agents and RAG Applications that actually solve business problems. Unlike generic bot builders, I use advanced frameworks like LangChain and CrewAI to create systems that can "think," plan, and execute tasks.
My Tech Stack & Expertise:
- Frameworks: LangChain, CrewAI, AutoGen, n8n
- Vector Databases: Pinecone, Weaviate, ChromaDB (Essential for RAG)
- LLMs: GPT-4o, Claude 3.5 Sonnet, Llama 3, Groq (High speed)
- Backend: Python, FastAPI,Nodejs
What I can build for you:
- Multi-Agent Systems: Agents that collaborate (e.g., a Researcher Agent + a Writer Agent).
- Custom RAG Chatbots: Chat with your PDF, CSV, or Notion database without hallucinations.
- SaaS MVP: Full-stack AI web apps using Next.js/React/Nuxtjs and Python.
Why work with me?
I don't just write scripts; I build scalable AI Architecture. Whether you need a simple automation or a complex Enterprise AI Solution, I deliver clean, production-ready code.
