Mac McCoy

I’m a dynamic AI Automation Specialist focused on bridging the gap between manual operations and AI-driven efficiency. I architect end-to-end workflows using n8n, Zapier, and the OpenAI API to eliminate redundant tasks and scale output, translating complex business needs into practical, self-sustaining automated solutions.

I build custom GPTs and sophisticated prompt structures—paired with prompt engineering techniques like Chain-of-Thought and N-Shot—while applying hallucination mitigation to keep automation reliable. My workflow orchestration includes advanced n8n (Custom Nodes/JSON), zero-touch pipelines, and multi-step API/Webhook integrations, supported by AI architecture, ETL, unstructured data transformation, sentiment analysis, and operational process auditing. Before this, I served as a Correctional Officer Sergeant with the State of Florida Dept. of Corrections, maintaining zero-breach operational continuity through rigorous access control and consistent adherence to Federal regulatory certifications—an ethic I bring into every automation I design.
