Self-reference, woven into the structure of AI services

AI Service Planner · PM, working across four domains — heritage culture, startups, financial IT and AI. The Threshold Recursive Isomorphism Hypothesis (TRIH), proposed in my bachelor’s thesis "Self-Reference and the Possibility of Mind", now carries into LLM-based service design and mechanistic-interpretability research.

Philosophy

Reduction and self-reference draw the essence out of complex systems.

  • Formal isomorphism

    Look past surface differences to formal isomorphism

  • Three-stage schema

    Trace structure through a three-stage schema: reduction → self-reference → emergence

  • Theory ↔ practice cross-checks

    Theory is validated by real deliverables; practice by theoretical coherence

DOMAIN 01

LLM Service Design

Reduce prompts to rules, let the model reference its own output, and observe the capabilities that emerge.

  • AI · LLM
  • LangChain · RAG
  • Prompt Design
  • MCP
DOMAIN 02

Financial Cloud Operations

Reduce requests into five layers, let the metrics verify themselves, and honor availability as a contract.

DOMAIN 03

Interdisciplinary Research · TRIH

Reduce four domains into a single three-stage formal model, and locate the point where that model contains itself.

Reduce ottchil and najeon into material rules, rewrite those rules through 3D modeling, and arrive at new form.
