Hello, I'm David, building under One Workflow Fixed. This introduction uses synthetic narration so I can show the work directly.

I build bounded automation systems with n8n, JavaScript, webhooks, and APIs. What drives me is turning ambiguous processes into reliable workflows with explicit pass or fail criteria.

My first proof is an AI Output Safety Gate. It validates schemas, enforces action and target allowlists, uses one bounded retry, and routes uncertainty to human review. Nine contract tests pass, and the workflow executes zero external actions.

My lead-handoff rescue proof normalizes current and legacy fields, blocks invalid records, and updates duplicate events instead of creating duplicate CRM entries.

I work best on scoped remote projects with clear inputs, outputs, edge cases, and documentation. I am seeking freelance or project-based collaboration, starting at thirty U.S. dollars per hour, or a fixed paid trial.

The attached one-pager and live portfolio contain self-directed sandbox and product evidence, not paid-client deployment history. Thank you for reviewing my application.
