I build AI automation that ships and keeps running — n8n & Make workflows, AI agents, and RAG chatbots — backed by 10+ years of Python automation and data engineering for international clients. Most freelancers can drag-and-drop a no-code flow. Few can handle the messy data underneath — pulling it, cleaning it, and feeding it reliably into your systems. That's the part I've done at scale for a decade, and it's why my automations don't break after week two. What I can build for you: ▸ AI automation & agents — n8n / Make workflows with AI steps that classify, extract, summarize, and decide; multi-step AI agents that use tools and take action (Claude, GPT, Gemini). ▸ RAG chatbots — assistants that answer from your own documents and data, with every answer grounded in a cited source (PostgreSQL/pgvector, embeddings, hybrid search). ▸ Data pipelines & web scraping — large-scale extraction, ETL, enrichment, and monitoring with Python, Scrapy, Selenium, and Playwright, including proxies and anti-bot handling. ▸ Integrations — HubSpot, GoHighLevel, Airtable, Google Workspace, Slack, Telegram/WhatsApp, REST APIs, and webhooks. How I work: consult first, then automate — so we fix the real bottleneck, not just the obvious one. Every build ships with source code, documentation, and error handling, so it survives the handoff. Clear, proactive communication on US-friendly hours. Tell me which workflow is costing you the most time, and I'll show you exactly how I'd automate it.
