About Me

AI Engineer

I build robust applications on top of foundation models — starting with the simplest effective lever and scaling only when needed: Prompt → RAG → Fine-Tuning → Agents. My edge: production pragmatism and governance (HIPAA, GDPR, EU AI Act).

Decision Framework

  • Behavior Assessment — If format/tone/reasoning fails → Fine-Tuning.
  • Information Assessment — If knowledge is missing → RAG.
  • When both behavior & info are sufficient → Prompt Engineering.
  • For dynamic, multi-step work → Agentic orchestration.
