AI & Automation Engineer | n8n Workflows, Autonomous Agents & Custom RAG Pipelines
About
I am an AI and Software Engineer specializing in building intelligent workflow automations with n8n, autonomous AI agents, and custom API integrations. I help businesses move beyond simple automations by embedding production-grade AI into their workflows. My focus is on turning manual, repetitive processes into reliable, self-operating systems: - AI Agents and LLM Orchestration: Designing multi-step reasoning workflows using n8n AI nodes, LangChain concepts, dynamic tool calling, and local or cloud models (OpenAI, Anthropic, Ollama). - Production RAG and Knowledge Bases: Automated document ingestion, smart chunking, and semantic search integration with vector databases like Qdrant and PostgreSQL (pgvector). - Custom Integrations and Webhooks: Connecting disparate systems via REST APIs, custom webhooks, Python scripts, and database sync. - Business Process Automation: Seamless workflows across communication and data platforms including Telegram, WhatsApp, Slack, Gmail, Google Sheets, Airtable, Notion, and CRMs. - Infrastructure and Reliability: Self-hosted n8n setups on Docker, structured error handling, clean state management, and scalable data flows. Whether you need an intelligent assistant, an automated lead processing pipeline, or complex data synchronization across multiple tools, I deliver robust, well-documented architectures built to scale.
