Hi n8n community,
I’m Aman Manikpuri, a full-stack developer and AI/LLM specialist available for freelance projects, contract work, or full-time opportunities involving n8n, AI agents, and production automation systems.
I build reliable business automations with n8n and extend them with LangChain, LangGraph, RAG, tool calling, memory, and custom backend services when a workflow requires more advanced orchestration.
I can help with:
- Production-grade n8n workflows using webhooks, REST APIs, databases, authentication, retries, error handling, and logging
- AI agents with LangChain and LangGraph
- Multi-agent systems with shared state and controlled handoffs
- RAG pipelines using ChromaDB, FAISS, Pinecone, or custom vector search
- Local and private AI deployments using Ollama, Docker, and open-source models
- LLM evaluation, hallucination detection, grounding, relevance, faithfulness, and toxicity testing
- FastAPI services and custom Python integrations around n8n
- Human-in-the-loop approvals and business process automation
- Monitoring dashboards, alerting, execution tracking, and production documentation
My professional background includes:
- More than two years of full-stack development experience with React, Node.js, Express.js, MySQL, REST APIs, authentication, and third-party integrations
- AI/LLM analysis experience focused on response quality, RAG grounding, hallucination reduction, instruction adherence, and structured generation
- Experience with Python, FastAPI, Docker, AWS, SQL, MongoDB, ChromaDB, FAISS, and Pinecone
I focus on building systems that are not only impressive in a demo, but also maintainable, testable, observable, and suitable for real business use.
If you need help turning a manual process into an n8n automation, adding an AI agent to an existing workflow, or designing a production-ready multi-agent system, feel free to reply here or send me a direct message.
