One person owns the whole flow: the database, the workflows, the AI agent and the integrations between them. 📊 Recent work: ⚡ Lead automation: Meta, TikTok and Google Ads leads sent to the CRM via n8n, qualified and assigned automatically. 🤖 RAG chatbot: n8n + OpenAI + Qdrant + Telegram, answering from the client's own knowledge base. 🔎 AI web scraping and data enrichment: n8n + Apify + OpenAI. 🧾 Odoo expense report automation, ticketing + CRM automation, payment processing workflows in n8n. ⭐ Top Rated, 100% Job Success, replies within 4 hours, Lviv (UTC+2). n8n is my main automation tool. As an n8n Expert, n8n Developer and n8n Automation Specialist I build n8n workflows end to end: webhooks, API integrations, HTTP Request nodes, custom JavaScript Code nodes, sub-workflows, retries and error handling, so an n8n automation does not silently fail at 3am. I set up self-hosted n8n on Docker (VPS, queue mode, backups) or n8n Cloud, and migrate automations from Zapier and Make (Integromat) to n8n when the task bill gets too high. Typical n8n workflow automation: lead capture and routing, CRM automation (HubSpot, Pipedrive, GoHighLevel, Odoo), Google Sheets and Airtable sync, Slack and Telegram notifications, email automation, invoice and payment processing, reporting. As an AI Automation Engineer, AI Agent Developer and AI Workflow Automation specialist I add OpenAI, Claude and other LLMs to n8n: AI agents with tools and memory, RAG systems on Qdrant, Pinecone or Supabase pgvector, AI chatbots for Telegram, WhatsApp and websites, document parsing and data extraction, AI lead qualification. As an AI Voice Agent Developer I build Vapi voice agents that answer calls, book meetings and update the CRM. Supabase is the backend behind these automations. As a Supabase Developer and Supabase Expert I design PostgreSQL schemas, Row Level Security (RLS) policies, Supabase Auth, Edge Functions, Storage, Realtime and database triggers that call n8n webhooks. n8n + Supabase is my default stack for AI apps: Supabase stores users, leads and vector embeddings (pgvector), n8n runs the logic. I also fix Supabase issues: RLS permission errors, failed or slow queries and data sync problems, and take over Supabase projects started in Lovable, Bolt, v0 or Bubble. As a Backend Developer with PHP, Laravel and Node.js experience I write custom APIs when an automation needs one, integrate payment systems like Stripe, and migrate legacy code (CodeIgniter 3 → 4). As a Business Process Automation and API Integration specialist I start with an audit of your current tools, then automate the step that costs your team the most time. Also in scope: Make and Zapier automation, Python scripts, web scraping with Apify, ETL and data pipelines, PostgreSQL optimization, Docker deployment, workflow documentation and handover. Send me the process you want to automate or the Supabase issue you're stuck on. I'll reply with a short plan and the first workflow I'd build.
