Über mich
Toptal-vetted AI engineer (top 3%) — I build AI agents, chatbots, automations, and voice assistants that actually work in production, not just demos. I've shipped AI agents with LangChain, LangGraph & MCP, RAG chatbots grounded on real data with citations, a live multilingual voice assistant, and Make.com/n8n automations with self-healing error handling. Stack: Python, LangChain/LangGraph, FastAPI, Next.js, OpenAI & Claude, pgvector/Supabase, Make.com, n8n. Message me before you order — tell me what you're building and I'll give you a straight answer on how I'd approach it.... Mehr lesen

AI Automation Engineer

Toptal • Freiberufler

Feb 2026 - Present • 8 mos

Design and build custom AI automations and AI agents for businesses across the US, UK, and Europe. • Built end-to-end workflow automations in n8n, Make, and Zapier — connecting CRMs, email, WhatsApp, Slack, and Google Sheets to eliminate manual data entry and follow-ups. • Developed AI agents and RAG chatbots using the OpenAI and Anthropic APIs, trained on client data to handle support, lead qualification, and internal Q&A 24/7. • Delivered AI voice agents (Vapi, Retell, Twilio) that answer calls, book appointments, and route leads automatically. • Automated lead generation, web scraping, and data enrichment pipelines that saved clients dozens of hours per week. • Owned projects end-to-end: scoping, building, testing, documentation, and post-delivery support with error handling for reliability. Tools: n8n, Make, Zapier, Python, OpenAI (GPT), Anthropic (Claude), LangChain, REST APIs.
