View Full PortfolioProfessional Summary
I build AI automation that survives contact with production — n8n workflows with real error branches and idempotency, controlled AI agents that stop and wait for a human before anything irreversible, and LLM integrations (Claude, OpenAI) wired into CRM, accounting, and field-service systems.
The reason those hold up is 18 years of platform and DevOps work underneath: PostgreSQL/Supabase, GitOps CI/CD, and serverless edge deployments. I know what breaks at 3am, so I build the retry, the fallback, and the alert before the demo.

Proof, Not Claims
Anyone can list "AI automation" on a CV. This is the code — importable n8n workflows and a working agent service, with the failure handling included.
4 importable n8n workflows (55 nodes) + a Claude agent whose sensitive actions park in Postgres and wait for a signed human approval, then resume in a different process hours later.
