Cover image for AI Workflow Reliability - public-safe
AI Workflow Reliability - public-safe automation first-slice snapshot. I build AI workflow prototypes where Claude, OpenAI, n8n, Make, and API handoffs are one part of a traceable system, not the source of truth. The first slice maps inputs, the model step, validation rules, fallback/review routing, and operator-readable handoff notes. Useful for: API/webhook automation with messy inputs n8n, Make, or Zapier reliability cleanup LLM outputs that need schema checks and audit trails small discovery milestones before a larger build Public-safe note: this is a portfolio snapshot of my delivery approach, not a private client screenshot.
