SUMMARY

  I turn AI from prompt experiments into production systems. I design
  LLM-powered applications and the workflow infrastructure around them:
  backend logic, prompt architecture, and API integrations connecting AI
  models to CRMs, marketing platforms, and the tools a business runs on.
  8+ years in digital systems, SaaS, and business automation.
