Hi! I'm Le Toan — an AI Agent Automation Architect & Data Specialist with over 5 years of experience. I help agencies and businesses scale by combining custom AI Workflows (n8n, GoHighLevel) with advanced Data Analytics (Power BI & Looker Studio). Whether you need end-to-end n8n workflow automation or high-impact interactive dashboards (Power BI & Looker Studio), I deliver high-precision solutions that eliminate manual tasks and accelerate business growth. 💼 WORK EXPERIENCE & TECHNICAL HIGHLIGHTS ⚡ Automation & AI Workflows (n8n, GoHighLevel & Webhooks/APIs Integration) AI-Powered Automation & CRM Pipelines: Designed and operated end-to-end workflows integrating n8n, GoHighLevel (GHL), AI models, and APIs to automate multi-step lead capture, appointment booking, and media rendering. GoHighLevel (GHL) Ecosystem & Middleware: Built custom GHL architectures—configuring sub-accounts, snapshots, custom pipelines, and connecting GHL via Webhooks/APIs to self-hosted n8n engines and Conversational AI (Vapi, Retell, OpenAI) for automated lead qualification. Event-Driven Operations Backend: Built real-time backend architectures (e.g., EV Fleet Management using AppSheet/GHL Webhooks connected to a self-hosted n8n engine for vehicle tracking, automated logs, and CRM syncing). Custom API & Webhooks: Engineered custom integrations between third-party SaaS (GHL, Stripe, Meta Ads), REST APIs, and databases (PostgreSQL, BigQuery) using JavaScript/Python in n8n. Web Scraping & Data Engineering Pipelines: Built resilient, automated web scraping workflows (utilizing Firecrawl, Apify, and custom scripts) to extract unstructured web data, clean and normalize complex JSON/text payloads, and load them seamlessly into databases (PostgreSQL, Supabase, BigQuery) and CRMs for downstream analytics and AI consumption. 📊 Data Engineering & Business Intelligence Executive BI Dashboards: Designed interactive Power BI & Looker Studio dashboards utilizing Star Schema data modeling and advanced DAX measures for financial, sales, and operational analytics.
