Automation Engineer | AI Orchestration | Workflow Architecture

Automation Engineer with 29+ years building software across enterprise and startup environments. Currently running Velocity BPA, where I built a Zero-Human Company (ZHC) platform: n8n workflows, custom MCP servers, and Claude AI working together to handle business operations from opportunity discovery through code generation and npm publishing. The pipeline has produced 200+ production n8n community nodes so far.

Before that, I spent 3+ years at AbbVie leading UI/UX platform work across 130+ global sites, and have shipped production code at CVS/Aetna, Pandora, Samsung, and Apple. I work primarily in TypeScript/Node.js, have real depth in API integrations and workflow orchestration, and have been in crypto/blockchain since 2013. n8n certified (Level 1 & 2).

Zero-Human Company (ZHC) Platform

  • Built and deployed 4 MCP (Model Context Protocol) servers that let Claude AI manage 168+ projects across Airtable, GitHub, n8n, and AWS without manual intervention
  • Designed the overall ZHC operations platform: AI handles opportunity discovery, code generation, publishing, and client management while I provide strategic direction and approvals
  • Created an approval-gate system so AI can run independently on routine tasks but flags key decisions for human review

Node Development Pipeline

  • Built a 45-node n8n workflow that takes a service name as input and outputs a complete, publishable n8n community node package in 4 to 11 minutes (previously days of manual work)
  • Used this pipeline to ship 200+ production n8n nodes covering blockchain/DeFi, enterprise SaaS, fintech, and DevOps
  • Wrote the prompt engineering layer for Claude AI (Sonnet for code gen, Opus for architecture decisions)
  • Added parallel execution with Promise.all so the pipeline generates multiple resources at once, handling 10 to 20+ resources per node complete with TypeScript source, Jest tests, and GitHub Actions CI/CD

API Change Monitor

  • Built a 3-tier monitoring system that watches all 168+ published integrations for upstream API changes: OpenAPI spec diffing, documentation page hashing, and GitHub release tracking
  • Claude AI analyzes detected changes and scores them 0 to 100. Anything scoring 60+ triggers an automatic rebuild through the pipeline
