About

Builds n8n and LLM automation, working as overflow capacity for agencies rather than chasing direct clients. Recent production work: an n8n and LLM check-in and reporting agent where every integration sits behind a config-swappable adapter, with a review queue for uncertain output and a dead-letter path for failed sends. Also delivered a live Twilio WhatsApp number cutover with no dropped inbound messages, plus OAuth and webhook auth, Postgres and Google Workspace integrations. 15 hours a week, UK based.
