I build production-ready automation systems — not demos — using n8n, LLMs (OpenAI, Gemini, Claude), and AI agent frameworks. If you have a messy manual process (documents, emails, CRM, onboarding, reporting) and want it running reliably in the background, that’s what I do.
A few things I’ve shipped:
- An invoice automation pipeline (n8n + Mistral OCR + Gemini) that reads PDFs from email, extracts structured data, logs it to Sheets, and archives it — zero manual entry.
- A multi-agent business automation system (CrewAI) with 8 specialist agents across HR and Admin, routed by a central orchestrator, with human-in-the-loop approval before any action fires.
- A document processing pipeline hitting >95% OCR accuracy and >85% categorization accuracy, with GPU-accelerated parallel processing (15-30s/doc).
- Multi-branch client onboarding automation: form → CRM → staged email sequences → Slack/Asana/Drive, with waits and conditional logic, not a straight line.
Stack: n8n, Python, Google Apps Script, SQL, Docker, REST APIs/webhooks, OpenAI/Gemini/Claude APIs, Google Workspace, n8n-MCP (Claude-assisted workflow building).
What I’m looking for: freelance/contract automation projects — lead capture pipelines, document/OCR workflows, AI agent systems, CRM/onboarding automation, or fixing/auditing existing n8n workflows that aren’t stable yet.
