What I do

Automation & AI integration — workflow automation that actually ships: n8n, Python, Claude/MCP tooling, LLM agents. I design it, build it, and hand it over working.

Systems & API integration — making platforms cooperate: REST/SOAP, SSO/SAML, webhooks, ETL, CRM and SaaS integrations. Eleven years at ServiceNow doing exactly this, at enterprise scale.

Hard problems — the question nobody has an answer to. Stuck systems, failed integrations, verdicts your suppliers can’t give — investigated, diagnosed, answered.
