About this gig
Looking to eliminate manual work with intelligent n8n workflows, autonomous AI agents, or custom OpenAI API integrations? I engineer production-ready AI automations, webhook pipelines, and custom LLM integrations using n8n, Python, FastAPI, LangChain, and OpenAI.
Production AI & Automation Systems We Have Built:
- Assistant Agent: Autonomous multi-step AI agent system that plans tasks, connects to external tools, and automates browser and API operations.
- Automated OCR & Document Pipelines (ExpenseWaale): Intelligent extraction workflows that parse receipts, PDFs, and emails into structured databases.
- Real-Time Webhook Engines (Liquid Signal): Live data ingestion and instant multi-channel alert pipelines.
What I Will Build For You:
- n8n LangChain AI Agents: Tool-calling AI agents with conversation memory, live web search, and RAG vector databases (Pinecone, Supabase, Qdrant).
- OpenAI, Claude & Whisper Integrations: Custom GPT structured JSON outputs, Whisper voice-note transcription, and vision/OCR document parsing.
- Multi-App & CRM Sync: Connect WhatsApp, Slack, Gmail, HubSpot, Notion, Airtable, Google Sheets, PostgreSQL, and custom REST APIs.

FAQ
Are API and hosting costs included?
No. You provide your own n8n hosting and API accounts. Any OpenAI usage or third-party subscription fees are paid directly by you. I will explain the required tools before we agree on the workflow.
Can you build tool-calling AI agents and RAG chatbots directly inside n8n?
Yes, I build advanced n8n AI Agent workflows using LangChain nodes, OpenAI/Claude models, conversation memory, and vector databases so your agent can search your company data and trigger live tools.
Can you connect custom APIs that do not have a built-in n8n node?
Absolutely. I use custom HTTP Request nodes, webhooks, and JavaScript/Python code nodes inside n8n to integrate any REST or GraphQL API.
Do you help with self-hosted n8n setup as well as n8n Cloud?
Yes, I work with both n8n Cloud and self-hosted Docker/VPS deployments, and I provide the complete exported workflow JSON file with every delivery.
